We have a lovely calm bedtime routine, I do all the right things. But every night it takes 15 month old DS at least an hour to go to sleep, messing on and crying and screaming. He's tired, but he's not overtired. Naps are great. No teeth. Not ill. Eats well. At the grandparents, they do a very similar routine and he goes in the cot and falls asleep like a dream in 15 minutes.
It's driving me fucking insane and taking over my whole night. What am I doing wrong?!?!?!
