I have a 7 week old DS. A couple of weeks ago I started really struggling with daytime naps - he would go to sleep OK usually but always seemed to be in a light sleep and require constant rocking to remain asleep (he has his naps in a Moses basket that rocks). I could sometimes rock enough to keep him asleep up to 2 hours, but he would be in such a light sleep and disturbed so easily. Often he slept somewhere between 20 minutes and 45 minutes. At this point I had an awake time of 45 minutes which sounded about right for his age.
I experimented a bit with awake times and I am now finding if he stays awake about 1 hour 45 minutes he still goes to sleep easily and will sleep for 2-3 hours with only a little occasional rocking and seemingly in a much deeper sleep. He is pretty cheery during the day, although he has a terrible witching 'hour' of screaming from about 7pm - 10pm, but this hasn't got noticeably worse since I changed his awake times. Sometimes he seems grouchy/tired a bit earlier in which case I put him down to nap sooner.
I feel like this works better for him, but 1 hour 45 just seems such a long time for a newborn to be awake. From my memory my older daughter slept pretty much constantly apart from feeding at this age. I worry he yawns a lot, but I don't think his yawning has increased and my daughter always yawned a lot so maybe I just have yawny babies!
I guess I was just looking for other people's ideas/experiences as I am really bad at trusting my parenting instincts, and I am worried he is suddenly going to become overly tired and I am going to massively regret it!
