So DS sometimes slept through when he was teeny tiny but has never slept through again since he was 3 months. He's now 15 months, and wakes one or two times a night, once my hubby puts him down in the early part of the night but if there's a second later waking, normally around 2-4am I feed him. Yes, yes admire my sparkly beautiful rod for my own back... on similar lines he still gets hysterical if you put him in his cot wide awake, so I tend to feed him to sleep or else cuddle and sing to him til he's very snoozy and then tuck him in. My partner can get him off with a shush pat, but he'll no longer fall asleep for me doing that.
Anyway we're almost resigned to this, although possibly considering nightweaning over xmas, but was talking to friends with more experience and also my HV and they said it was their more gifted/inquistive kids who were the worst sleepers. They were probably just being nice and offering me some consolation for no decent sleep in over a year, but do you think it tends to be the brighter kids who have the most difficulties sleeping?
