I am really struggling to get my 16 week old baby to take naps during the day at home for anything longer than 10mins. She generally has no trouble sleeping through the night in her cot but she just does not know how to nap during the day unless she is in motion in the car or in the pram. I can see she's tired but she just fights it and is grouchy as a result, and I feel like it's getting progressively worse because today she didn't sleep longer then 30min even when she was in motion in the car, and then wouldn't sleep at all when I was pushing her around in the pram. It's really starting to stress me out, does anyone have any advice?
