Do I need to be concerned?
He can roll onto his side, but doesn't bother much. He has never rolled by himself in either direction.
He's doing everything else - stands with weight in his legs, holds things and passes from one hand to the other, babbles consonant and vowel sounds... he's really sociable. He can also sit up unsupported. But he's completely missed this milestone. It's meant to happen at 5 months I think but he's closer to 7 months.
I mentioned it to HV on the phone who seemed really unconcerned but said as big sis is in for her 2yo review they'll see him too.
Anyone else have experience of this?
