DS3 who is 19mo has never slept through.
He goes to sleep at about 7.30/8pm, wakes at 10.30/12 and ends up in our bed till 6ish.
when he goes to sleep he has a bottle, on my lap, sitting on the sofa bed in his room, when he's asleep I pop him in his cot (or he pings up, and I cuddle him again - repeat as required).
Then when he wakes up, generally, he's inconsolable and the only way to get him back to sleep is to bring him into our bed, where he hits the pillow and sleeps almost immeditaley - if I try and soothe him whilst he's in his cot, if he's already standing up, it's too late. If I cuddle him he'll sleep, but won't settle back in his cot. I am so tired! Any ideas?? He has one nap in the afternoon, normally about 1.5h-2hr long.
