Austin will be 10 months tomorrow and most days he goes by that exact nap schedule. He will let you know when he is ready to go down to fewer naps a day. One thing that I swear by to make his bedtime more predictable is a bedtime routine! At 7:30 every night the boys take a bath. After bath they get changed into jammies, have a snack, say good night, and are in bed by 8. They both thrive on it and my husband and I are able to plan time to watch a movie or something.
