Ok, baby has been in a pretty good routine for a while. Bed for 8, sometimes earlier, wakes once or twice and has a feed around 4 and then is pretty much up for the day at 5.30. I can cope with it but I'm wondering if I changed bed time to later would he sleep longer in the morning? Even just by and hour and a half, so if I put him to bed around 9 would he stay in bed till 6.30? I know it's not as simple as that but in theory should it work? Does anyone else put baby to bed a bit later? He is 17 weeks. X
