What, exactly, is a 'demanding' baby? My little one is 4and a half months, and will sleep from 6.30pm to 7.30am quite happily. I do realise this is a situation many would give their right arm for.... however...the payback seems to be that during waking hours he wants constant attention, seems to get bored and frustrated easily and will only sleep, if at all, for a maximum of 20 mins twice in the day.He also cries a fair bit. Come 7pm I'm shattered, and I can't get much done in the day because life revolves totally around him. Should I try and change things, or just shut up and put up??!!!
