My 9 month old takes two naps a day- one at 9:30ish for about 45 minutes to an hour and a second nap at 1:30ish for about an hour and a half. Recently she has stopped showing tired signs for the second nap and after a period of time I put her down anyway and she easily falls asleep. When she wakes up from this nap she's often cranky. Any thoughts? When did your LO drop their second nap?
