Crawling doesn't necessarily mean on hands and knees either. My girl is a bum scooter and really didn't start moving until she was 11 months I think, maybe a little younger.

She is also not trying to stand or walk, we try to encourage her but she is just not interested.

Tell your friend not to worry, maybe her child is busy developing in other areas?

FWIW DD baby cousin is 3 months younger and she is pulling herself to standing and doing amazing physical things that our DD is no where near. BUT our DD's fine motor skills at the same age as her cousin have always been FAR more advanced.

Kids develop at different rates and stages, no two can or SHOULD be compared. I am sure her baby is just fine and if she really looked at her and needed to compare to the other kids then maybe she should take a close look at the areas that the baby has grown in rather than the areas she hasn't.
