Alot of the babies in DD2 baby group are all rolling at 3 months. DD is no where near interested or even tries to roll. DD1 rolled at 16 weeks exactly.

All kids develop at different times. I get emails to telling me what my child 'should' be doing at certain ages and i used to get all upset if DD1 wasnt doing it. but in the end i realised my kids will do things when they are ready and those emails are guidelines..and that everyone elses kids may develop different things and at diff times to mine.

DD1 was saying words before all the others in her group...but she walked later etc.

Dont take it to heart....your DS will roll...and then u will wish he never learnt
