Hi hun he might be a little young to be on 2 naps but it's not unheard of at all. My LO dropped to 2 naps around 7months. How long has he been on the 2 naps? I think perhaps he might be a little OT by BT if he's doing only a 2HR A in the morning then a 2.5hr A then a 3Hr A? But given you are getting a good 1.5hr nap out of each A time I am not sure honestly. What is he like when he wakes up and how does he get back to sleep?
