Hi! Im kind of going through the same thing too....but my baby is now 14 months old. I do remember that he went through a funny early waking phrase at about 11 months, and we also thought about reducing his nap time. It eventually worked (that is, not waking at 5-6 am-he now wakes on average at 6.45-7...VERY reasonable i think!) by doing the adviced later nap...and we only let him sleep for an hour in the morning, and an hour to an hour and a half in the afternoon. At the moment we are trying to cut out the morning nap. It works really well sometimes. We have to push him through a bit late morning, and give him his lunch at 12, then he gets a bit of a sugar rush from the food and ends up being able to stay up that extra hour, and he goes down at about 1.15. We then lewt him sleep as long as he wants, which is usually just less than two hours. We are no way near the finishing line, but i think the strategy works. I would recommend doing it in stages. Try reducing the nap times, for two naps a day and hope that he wakes at little later. Then implement the one nap plan....give it a go and see what happens. I pass on my sympathy, as I know how utterly exhausting early risers are! Be brave! It wont last forever! Hang in there!
