Hi there! My 2.5 year old is going through a funky nap phase right now. About 2 months ago she started to do the same thing, although not as bad as right now and then went back to her regular napping. Last time she would skip a nap once a week and some days take up until 2/3 to fall asleep for her nap, then about 2 weeks later she just went back to her normal 1-3 nap.
This time around she is skipping her naps at least 3x a week and on other days she is taking up until 2/3pm to fall asleep. The only days she falls asleep at 1 is a day after she skipped her nap the day before. She is becoming extremely irritable these last few days and I know she is completely exhausted.
I have been waking her in the morning at 7am for over 2 months now because I noticed that if she slept later (730/8) it made naps very difficult. I put her down at 12:45 every day and before she used to be asleep by 1:30 the latest. When she falls asleep at 2 or 3 I wake her by 330/345. I always do bed at 7:45 pm even on the days when she skips naps because I found that if I do early bedtime on those days she will not nap again the next day. I feel like she is getting maxed out on night sleep sometimes and then her drive to nap is very low. I think if she does more than 11 at night she will not sleep.
Should I be limiting her nap to 1.5 hours and see if that helps? I am not sure what to do at this point, but it seems she still needs her naps because she is getting very cranky and I want to hold on to nap time as long as possible--figures this happens when I am due with baby #2 in 4 weeks! I always leave her in her crib up to 2 hours even if she doesn't sleep.
