9-Month-Old’s Developmental Milestones: A Complete Guide
Your baby’s bum and belly will start to stick out.
This has nothing to do with your baby getting milk drunk too many times. And it has nothing to do with your baby inheriting a big booty from one of your sides of the family. Pampers reports that at this stage of development, it’s normal for your little guy/girl’s belly and bum to stick out a little when he/she begins to stand up. It has to do with your baby getting comfortable standing on his/her two feet. Once he/she does, the alignment will straighten up and your little one will look less like he/she is getting ready to twerk. It’s normally during a kid’s second year he/she will fully straighten up.
