When does it usually happen?
DS is 9 months old and usually has 2 sleeps a day, one around 9:30 and one around 2pm, but lately his morning sleep has been later and longer (2-2.5 hours) at around 10:30am and he hasn't been tired enough for his afternoon nap until 3:30-4. The problem with that is if he sleeps then, even if it is only for 20 minutes, he won't go to sleep for bed until 8:30-9. So I am thinking it might be time to consolidate and move his big nap to around 11am to see him through to night time, but I am not sure if 9 months is too young? All the babies I nanny for didn't go to 1 sleep until past one I think!
