my ds (6 months today!) will not sleep for more than 30 mins at a time during the day. i know this is a common problem. will he grow out of it or do i need to do something to help him sleep for longer? I always try and put him down in his cot but he will sleep longer if in his pram or on me. he won't feed properly if he's tired (which is all the time because of the short naps) but he won't sleep for long if he's hungry!
