My DS is 16 weeks old. He is a good night time sleeper, he is usually in bed by 7.30pm and gets up at around 8.30am, with 2 or 3 feeds in that time ( he is EBF) - he goes to bed easily & settles easily after the feeds.
But in the daytime, he hardly sleeps at all. He often has a late morning nap of around 45 minutes, but for the rest of the day he will regularly have 3 or 4 mini-catnaps of 10-20 minutes (usually on my lap after a feed, in his swing, or in the car). However, he is usually happy and alert and it is impossible to persuade him to sleep for longer - he just wakes up! He yawns all the time but other than that shows no sign of being sleepy.
Everyone else seems to have babies that sleep for 3 or 4 hours throughout the daytime. I'm worried that he's not getting enough sleep, but if he doesn't seem to need it, is that ok?
