I was getting a bit anxious that little one is now 3 and a half months old and doesn't yet do mini push-ups or roll over as suggested by www.babycentre.co.uk (the website I've been using since pregnancy to follow my baby's development). I know I shouldn't worry as all babies go at their own rhythm and can develop quickly for some things (he started smiling at 2 weeks) but I'm sure it's normal for a mother to feel envious of other babies already 'rolling' and who are slightly younger than him!
I place him on his belly every day but only for a few minutes until he gets annoyed... Anyone have some tips for improving this development? I've tried 'tempting' him forward with toys and today he has improved by slightly lifting his head off the mat a few times! Hooray :)
