PFB so not sure about this
: My son 5.5m has not yet seemed interested in rolling in either direction. I know theres still time yet but I'm not sure he's going to bother. On his back he will grab his toes and lean over, but not flip. On his front he leans back and tries lifting his bum, twist his shoulders and head and gets bored and screams.
TBH he is far more interested in sitting and standing (with support,obv) he just wants to be on his feet all the time.
I'm not concerned as such as he has pretty strong legs and neck muscles, but people are starting to ask when he first rolled, is he rolling both ways yet? and "you'll have to stop using the changing station cos he'll fall off"
Should I be worried yet? Or not at all? Are there some babies who just bypass some milestones?
