I was twenty weeks pregnant with my second baby when my first child turned into a tiny monster.
One morning, my three-and-a-half-year-old daughter woke up and seemed to forget how to be a person. She looked at her oatmeal and screamed like I had served her a bowl of spiders. She babbled in a language that sounded like English but wasn’t. She hit me in the shin with a wooden block because I poured the milk before she was ready.
I stood in the kitchen, one hand on my growing belly, the other holding a sippy cup, and I thought: Who is this child?
I was exhausted. I was hormonal. I had spent the last eighteen months feeling like I had finally figured out the toddler thing. We had routines. We had rhythms. She could use a fork. She could tell me when she needed to pee. And then, in the span of what felt like a single week, she regressed into a whining, hitting, gibberish-speaking creature I barely recognized.
I called my mom crying. I texted my best friend. I Googled “3.5 year old regression” at 2 a.m. while my daughter slept peacefully, looking like an angel who had never thrown a block at anyone’s shins.
And here is what I learned, not from a parenting book or a pediatrician, but from living through it, messing up, apologizing, and trying again the next day.
The Gibberish Isn’t Random
My daughter started speaking in what I called “nonsense loops.” She would look at me with serious eyes and say something like, “Bippity boppity boo, mama, the couch is crying, the couch is crying, okay? Okay?”
At first I laughed. Then I got annoyed. Then I got worried. Was something wrong? Was she hearing things? Did she need speech therapy?
But I started paying closer attention. The gibberish always happened at transition times. Right before nap. Right after I said, “Time to leave the park.” Right when I was on the phone and couldn’t focus on her.
She wasn’t losing language. She was overwhelmed by it. At 3.5, kids are flooded with new words, new rules, new expectations. Sometimes their brains can’t keep up. So they retreat into sounds that feel safe, sounds that don’t carry the weight of having to be correct.
One night I sat on the bathroom floor while she took a bath and I said, “I don’t understand the silly words, but I understand you’re trying to tell me something.” She looked at me, quiet for a second, and then said, clear as day, “I don’t want to go to bed.”
She could speak clearly. She just needed the pressure off first.
The Whining Is a Signal, Not a Weapon
I hate the whining. I will be honest. The high-pitched, grating, repetitive whine that sounds like a tiny smoke alarm with no off button. It makes my jaw clench. It makes me want to walk out of my own house.
And when you’re pregnant, everything is louder. Everything is more. The whining feels personal. It feels like she’s doing it on purpose to test me.
But I started noticing something. She didn’t whine when she was happy. She didn’t whine when she felt connected. She whined when she was tired, hungry, overstimulated, or feeling pushed away. And at 3.5, kids feel pushed away a lot. They sense the new baby coming. They sense mom is tired. They sense they aren’t the center of the universe anymore, and they don’t have the words to say, “I’m scared I’m losing you.”
So they whine.
It doesn’t mean you have to fix it. But it helped me to stop interpreting the whine as an attack. It was more like a check engine light. Annoying? Yes. Important? Also yes.
The Aggression Comes From a Place of Helplessness
This was the hardest part for me. My daughter started hitting. Not often. But when she did, it was hard and fast and aimed at my face. One time she smacked me across the nose because I told her we were having chicken for dinner instead of pasta.
I wanted to cry. I wanted to yell. Sometimes I did yell. And then I felt guilty, and then she felt scared, and then we both sat on the floor feeling terrible.
Here’s what I eventually understood: hitting at this age isn’t cruelty. It’s panic. Kids at 3.5 have big feelings and small brakes. They don’t have the prefrontal cortex to stop themselves. They feel something intense, and their body acts before their brain can catch up.
When I was pregnant, my patience was thinner. My reactions were slower. I wasn’t catching her before she escalated, because I was too tired to see the warning signs. So her hitting got worse, because she needed me to help her stop, and I wasn’t showing up fast enough.
That’s not blame. That’s just the truth of survival mode.
Some preschoolers don’t hit because they’re angry. They hit because they’re overwhelmed and don’t know what else to do with their bodies.
I started sitting closer to her during triggering moments. I kept my hands visible and open. I said, “I won’t let you hit me. I’ll hold your hands until you feel safe.” And sometimes she screamed harder. And sometimes she collapsed into my lap and cried.
Both were progress.
The Tantrums Aren’t About the Thing
She lost her mind over a broken cracker. She sobbed because I put her shoes on the wrong feet first before fixing them. She threw herself on the floor of the grocery store because I wouldn’t let her eat a banana before paying for it.
I used to think, If I can just explain it well enough, she will understand and calm down. But that’s not how 3.5 works.
The tantrum isn’t about the cracker. It’s about the thousand tiny frustrations of being small. Of having no control over your day. Of being told what to eat, when to sleep, where to go, how to behave, all day long. The cracker is just the last straw.
When I was pregnant, I had even less tolerance for the tantrums. I would stand there, belly out, thinking, I am growing a human and you are screaming at me about a cracker. And that disconnect made me angry.
But what helped was realizing she didn’t know I was growing a human. She only knew that mom was tired, mom was slower, mom was less fun, mom was more irritable. She was reacting to my scarcity, even though I couldn’t see it.
The Regression Is a Developmental Pause, Not a Backslide
I kept thinking we were moving backward. That all our hard work was unraveling. That I had done something wrong.
But regression at 3.5 is actually a sign of growth. Their brains are rewiring. They are learning impulse control, emotional regulation, social rules. And before any big developmental leap, kids often fall apart. It’s like their system needs to reboot.
They can’t tell you they’re growing. They just feel confused and scared and out of control.
When my daughter started sleeping worse, eating less, and crying more, I stopped trying to fix it and started just holding space. I said, “I know this is hard. I’m here. We’ll get through it.”
It didn’t stop the regression. But it stopped me from fighting it.
What Didn’t Work
I tried rewards charts. I tried time-outs. I tried explaining feelings. I tried ignoring the behavior. I tried everything the internet told me to try.
Some of it worked for a day. Most of it didn’t.
The rewards chart made her more anxious. The time-outs made her feel abandoned. Explaining feelings just made her more frustrated because she didn’t have the words yet. Ignoring the behavior just made her act out louder.
I am not saying these tools are bad. But when your child is in the middle of a 3.5 year old regression, they need connection more than correction. And I didn’t have the capacity for connection all the time, because I was pregnant and tired and touched-out.
So some days, nothing worked. And that had to be okay.
What looked like bad behavior was sometimes just a kid who needed more help than I had left to give.
What Helped a Little
I started narrating our days out loud. Not asking her questions, just saying what was happening next. “We are going to finish this puzzle, then wash hands, then sit at the table. The milk is going in the cup. The cup is blue.”
It sounds silly. But it gave her brain time to prepare. Transitions got a tiny bit smoother.
I also stopped trying to correct the gibberish. I just said, “I hear you,” and waited. Sometimes she would switch back to real words. Sometimes she wouldn’t. Either way, she felt heard.
And I started apologizing when I lost my temper. Not explaining why I was right. Just saying, “I’m sorry I yelled. That scared you. I’m going to try again.”
She learned that adults mess up too. And that we can come back from it.
You Don’t Have to Love Every Stage
I don’t love this stage. I love my daughter. But I don’t love the whining and the hitting and the constant neediness when I am already running on empty.
And I think it’s okay to say that out loud.
Parenting a 3.5-year-old through a regression while pregnant is not a season of gentle vibes and Pinterest crafts. It’s survival. It’s gritting your teeth through the grocery store meltdown and then crying in the car. It’s loving your child with your whole heart and still wishing they would just stop talking for five minutes.
The regression will pass. I know that now. But in the middle of it, I needed permission to be annoyed. To be frustrated. To not have the right answer.
So here is your permission.
You are not ruining your child. You are not failing. You are in the messy middle of a huge transition, for both of you. And you are both going to be okay.
My daughter is four now. She still whines. She still has big feelings. But the gibberish is gone. The hitting is rare. She tells me, “Mama, I was so mad my body didn’t know what to do.”
And I tell her, “I know, baby. Sometimes my body doesn’t know what to do either.”
We are both still learning.
