DS is 12 weeks and so far I've been putting him down for a nap once he's been awake for an hour and 15-30 mins. He's generally been settling himself really well and napping brilliantly. But the last few days he's been really hard to settle. I wonder whether I should be leaving him for longer between naps now? Or is it more that he's more alert now so fighting sleep, but I should still be aiming to put him down after the same amount of time?
Any thoughts anyone?
