DD is 6 months old and I'm a FTM so everything is new and everything is a worry!
DD doesn't roll over and doesn't really show any interest in doing so. I try to encourage her and she's happy enough on her tummy for a short time, but doesn't make any effort to move around. She can't sit unaided either.
My HV told me that if she couldn't roll by 6 months it could be cause for concern. I'm also surrounded by mums with much younger babies who all seem to roll, sit, babble etc...
Am I worrying unnecessarily or should I be concerned?
