Izzy is 5 months and goes to bed at 7. She wake 1-3times a night for a feed and if she gets up before 7 its back to bed, usually wakes at 7-9 ready for the day!! If he is getting long day sleeps then he may not need longer nights? Izzy only has 3-4 one hour sleeps during the day! I think at this age they should be sleeping something like 14 hours all up. HtH!!!
