I know all babies develop at different rates and that's perfectly normal but i can't help but worry about my 8 month old.
She can't sit up unaided, has never rolled back to front, she rolled front to back once at 5 months and then never again! She isn't trying to hold her weight at all. When practicing sitting she just flings herself backwards, and doesn't bend her legs or lean forward to balance. She also just hates tummy time and will only do it for around 5 minutes before getting really worked up.
My son was sitting at 6 months and crawling before 8 months so it's kind of taken me by surprise that she just has no desire to move!
I guess i'm just wondering if i should just be happy to have a really chilled out baby or if i should be concerned.
Also any tips to encourage her would be appreciated :)
