Should You Split Twins for TK? Here’s What We Did—and Why There’s No One Right Answer

If you're a twin parent staring down the start of Transitional Kindergarten (TK) and wondering if you should separate your duo or keep them together, welcome to the club. This decision feels HUGE - and spoiler alert: there's no one-size-fits-all answer.

I’ve been there, overthinking every scenario, imagining every meltdown, and wondering if I'd scar them (or myself) for life. Here’s what we considered, what we chose, and what I’d tell any other twin parent trying to make the call...and here is a TikTok video about the same topic

First: Let’s Acknowledge the Pressure

Everyone has an opinion.Teachers. Other twin parents. That one lady at the park. 🙄 Some swear separating builds independence. Others say keeping them together offers comfort and stability. You know what I say? You know your kids better than anyone. Follow your gut.

What We Considered

1. Their Personalities

Do they feed off each other’s chaos? Or do they truly support each other? One of my twins is a little more reserved, the other’s the “I’ll lead the way” type. But here’s the twist—they both use each other as emotional support animals in unfamiliar settings. So splitting them felt like a dramatic plot twist in a show they weren’t ready for. Plus, it was a school transition for us - the thought being - keep them together in TK and then split them for Kindergarten.

2. The School’s Setup

Some schools don’t even give you a choice. Ours did, which meant cue the overthinking. (FWIW, I have read that even if your school doesn't allow it - you can push for it as the parent). We talked with their pre-school teachers, I read dozens of forums, grandparents, other twin parents, and their pediatrician. Getting their perspective on the pros and cons helped us zoom out and look at the big picture.

3. My Own Sanity

Real talk: separate classes = double the emails, double the schedules, double the birthday invites. I already live in a color-coded calendar nightmare. So yeah… that was a factor.

What We Chose (This Year, Anyway)

We kept them together.

And not because I’m too soft or afraid of change. Because this year, it made sense for our family. They’re still learning how to be apart. They’re still building confidence in group settings. And honestly? TK is a big enough transition without also losing your built-in buddy. Plus if we split them, it meant they would have different start times (an AM and PM class).

What We’re Watching For

This isn’t a forever decision - it’s a for right now decision.We’re keeping an eye on:

• Classroom behavior (Do they distract each other?)

• Social growth (Are they making other friends?)

• Independence (Can they handle things without relying on each other?)

If down the road it seems like they’d thrive more apart? We’ll pivot. That’s the beauty of parenting twins: we’re constantly adapting.

If You’re Still Deciding, Here’s My Advice

• Talk to your school and get their insight....but take it with a grain of salt

• Talk to your pre-school teacher or anyone else that has worked closely with them.

• Ask your pediatrician - for me, she offered the most helpful advice and she knows my daughters well.

• Watch your twins in new environments - are they brave together or braver apart?

• Don’t feel pressured to “do what most people do.”

• Know that whatever you choose can be changed. You're not stuck forever.

  
  

Final Thought: You’re Not a Bad Mom Either Way

Whether you split them, keep them together, or flip a coin (hey, we’ve all been there)...you’re making the best decision you can with what you know now. And that’s enough.

So give yourself some grace, give your twins a popsicle, and remember: you’ve already made it this far with TWO tiny humans at the same time. You’ve got this.
