My little girl has done this forever, fyi. She still can’t sit straight up from laying😂 I always say she’s being strong girl, going to have abs by the age of 1 😂😂😂😂 xx
Mines been trying to do sit ups for 2 weeks. He can sit up completely if he starts from propped up against for about 3 seconds now before he lays back down. Got more core muscles than me 😂
Yep. All part of their development 🥰
