I nap the ones in the morning that still need it ..... I try to get them down at 8 or 830 ...... When you start having a problem in the aft you can shorten it and then cut it out totally..... I have one 15 month old that occasionally needs an am nap if he gets up really early (4:30, or 5 am ) but if he gets up at 6 then he stays up till the aft nap and I have another 11mobth old that doesn't nap at all in the am because if he does then he only sleeps for 45 mins in the aft .... Every kid is different
