Dd is 8mo and about 3 weeks ago we sleep trained which went brilliantly with good length naps and sleeping through the night. She is still sleeping through the night but at least 1 of her naps in the day (she has 2) is now only 45 minutes. Its usually the morning nap and she will still have a good afternoon nap but can be both. I was just wondered if anyone a) had any idea why she is back to short naps and b) what can we do to lengthen it again? We follow wake windows etc. She is on the verge of crawling so could this possibly be the reason why? And we do crib hour so even when she wakes at the 45 minute mark she doesnt get taken out of the cot until the hour is up. Tia.
