My 11 month old has been taking great naps, two hours, twice a day. He doesn't fight naps at all, but I think he needs the late afternoon catnap and I can't get him to take it. Then I try an early bedtime and he really fights it. He doesn't fight his morning and afternoon naps, and I do the same pre-sleep routine for all sleep. I figure he's overtired by bedtime because he doesn't get that catnap in. Should I do PU/PD for a catnap? I feel like it takes 30-60 minutes for him to give in that way, which misses the window for the catnap.
