I've recently started to put my 15 wo DS in his cot for his daytime naps and he's doing great - sleeping 4 times a day and settling himself, but the success of the daytime naps seems to be affecting when he wakes up. He used to wake up at about 6.30/ 7 for a feed, and that's what we'd start the day, but now he seems to be wide awake at 5.30! As soon as I see signs of sleepiness (usually yawning, sometimes eye rubbing) I swaddle him and put him down. He seems to need about four naps, three of which last about 2 hours and the final one lasting about 40 mins. Is 2 hours too long and therefore the reason he's waking up so early? If so, should I wake him after 1.5 hours and then let him have a little 40 min snooze on the fourth nap? I would love to cut out the 40 min nap because it's often a bit too close to his bedtime, but I can't because he gets overtired and really cranky. Could the final nap be the problem, and if so, how do I cut this out when he's obviously tired and needs it? I'm confused.
