My 4 month old DD sleeps well at night but her daytime naps are really short. She’s started napping in her cot and can self settle and get off to sleep with a bit of reassurance (usually I just have to pop her dummy back in a couple of times), but her naps are only ever 45 minutes absolute maximum, usually about 20 or 30 minutes. I follow a few baby sleep consultants online and they all say a 4 m/o’s naps should be about an hour to two hours long. She always seems tired when she wakes up and is still rubbing her eyes and can be quite grumpy so I don’t think she’s getting enough sleep.
Her room is dark, we have white noise on; I always make sure she’s fed, winded and got a clean nappy before a nap. Does anyone know what might be causing the cat naps and how I can make them longer?
