You prop her up on the nursing pillow, or tuck her into the corner of the couch so she can see the room. And within seconds, she’s either sliding sideways or crying like you’ve wronged her somehow.
Okay, here’s what’s actually happening. Her body isn’t ready to hold itself up against gravity yet, and it’s telling you that, loudly.
Propped Sitting Isn’t the Same as Independent Sitting
I get why we do this. We want her to see the room, be part of things, hit that “sitting up” milestone we keep hearing about. So we grab the pillow and prop her up.
But here’s the thing. When her trunk and neck muscles haven’t built that strength on their own yet, gravity takes over. She slumps forward. She tips to one side or even falls right over and bonks her head. Or, what I often see is babies who just ‘sit’ and don’t really move! They look happy but they aren’t really developing their muscles because they aren’t moving (because if they do, they will fall over).
And if her nervous system doesn’t feel steady, that turns into frustration fast.
She’s not being difficult. Her body is working overtime just to stay upright in a position it hasn’t earned yet.
What She’s Actually Telling You
Every single thing your baby does is communication, even the fussing.
When she fights being propped up, she’s not stubborn and she’s not lazy. She’s telling you, in the only language she’s got, that this position is too much work right now.
I see this constantly in my clinic and in my mom-and-baby classes. Mamas feeling like they’re doing something wrong because their baby “hates sitting.” You’re not doing anything wrong. Sitting isn’t a box to check, it’s a skill her body builds on its own, through rolling, side-lying, and floor time. It shows up when she’s ready, not when the pillow says she is.
What to Do Instead
Skip the prop. Give her a comfortable blanket on the floor instead, somewhere she can move her arms and legs freely.
Put a toy just slightly out of reach on her side and let her work for it. When she has to shift her own weight and push through the floor to get there, that’s her brain and body building real stability together. No forcing. No pillows doing the work for her.
In addition to tummy time and reaching, pushing, pulling practice with unrestricted floor time play you can also support your baby with moving in and out of sitting. Here is my Youtube video where I share more about how to do this.
That’s the difference between propped and prepared.
What She’s Also Asking Me
Is propping my baby up with pillows bad for her spine?
A few minutes here and there isn’t going to hurt her. But leaning on pillows to hold her upright before her body can do that on its own can put real strain on a spine and neck that are still developing.
When should a baby sit up completely unassisted?
Most babies get there somewhere between 7 and 10 months. But the number matters way less than how much comfortable floor time she’s getting to build those foundations at her own pace.
What can I do instead of propping my baby to sit?
Let her play on her back and side on the floor. Rolling, pushing up, reaching, all of it builds trunk strength the way her body actually wants to build it. And focus on helping your baby get in and out of sitting rather than just ‘propping’.
