Is your baby sitting on their own yet??

Kari

My daughter will get in the sitting position on her own.. but, she sits in her knees (picture attached) is that normal?? My son always got in the sitting position in his own; sitting on his bottom. But my daughter always sits up on her knees. Can this effect her bone structure or anything?? I meant to bring it up to the doctor at her last check up but I forgot and her next check up isn’t until she’s one...
