DD is 3 months old and sleeps quite well at night. In the day she is doing a very short routine. Basically, she feeds, stays awake for about 45 minutes and then sleeps for about 45 minutes. This is even the case after a good night sleep. I am just going with it (have 22 month old too - and trying to keep life as stress free as possible), but she does seem very tired after the sleep at 12/1ish. Am I being cruel by not working harder at getting her back to sleep for longer at that nap? Or, will she just sort herself out?
