My son (5.5 months) sleeps about 12 hours straight every night, from 7-7.
However, I'm worried about his daytime naps. He used to sleep for a couple of hours in the morning or at lunchtime, but recently he's only sleeping for 45 mins (so one sleep cycle) at a time before waking up. It means he's only getting just over 2 hours of naps a day. He sleeps in his cot generally as he naps better there than in the pram.
How can I encourage him to sleep for longer?
