Bedtime for DS (11 months on Monday) for the past several months has been between 6:45 and 7:30 and he could usually be counted on to sleep until 7:00-7:30 the next day. The last week or so he has been going to bed at the same time but waking up at 6. Every day this has happened we change him, I'll nurse him and put him back down to see if he's still sleepy. He usually goes back down no trouble. We also noticed he's tossing and turning and having a lot of trouble going to sleep. Should we push bedtime back a little or maybe put him to bed earlier? Or is he just needing less sleep now? Is this a growth spurt maybe and he's just wanting to nurse more?
