That was the case with Isabella. She was 9 months when she dropped her catnap, so she had a nap at 9am, 12.30pm and the rest of the day off. She would be awake from 2pm till 6.30pm. Some try to space out the 2 nap so that A time is more or less the same throughout the day but she wouldn't fall asleep for her afternoon nap when I tried to extend it till even 1pm.... so I left it at 9 & 12.30pm
