Help! My 18month old boy is still very unsettled at night. He very occasionally sleeps through (about 7.45 until 7) but most nights he wakes at least once, usually 2 or 3 times. We're so tired from getting up to see to him. He often goes back to sleep after a drink of water but I don't know if he's now waking up out of habit for the water. We've tried all sorts of differetn things like shortening his sleep in the day (now about 11-12.30) and swapping his meals so he eats more later in the day but nothing seems to consistently work. Any ideas????
