My baby boy is nearly 15 weeks now and won't sleep anywhere but on me during the day. He goes down at bedtime nicely, the amount he sleeps varies between 8 and four hours but then he won't settle again. During the day he fights sleep so much, I've tried doing our bedtime routine, using blackout blinds, white noise, tried putting him down awake and leaving him until he cries (and then go straight to him) and I've tried rocking him to sleep and putting him down. No matter what I try he won't sleep longer than half an hour unless he's on me, he gets overtired and grumpy then. I've spent days just letting him catch up on sleep on me and trying again when he's not so overtired, I'm seriously running out of ideas! I know he's still little and I do love cuddling him while he sleeps but it's getting so I can't leave the house and I'm going stir crazy, does anyone have any advice please!?
