Hi all. My son is 5 months old and up until he was 4 months old he would take 3 good naps a day and sleep from 9pm until 5am have a feed and then sleep till 8 am. In the past month it is getting harder and harder to get him to nap in the day and he is now waking up every 2 hours at night. The only way he will settle is with breast feeding whereas previously he would suck his thumb which he now can't seem to find. Most of the time he will have one or two sucks and fall asleep so I know it's just comforting rather than hunger. He doesn't appear to be teething and gallop or teething powders make no difference. We've changed nothing about his bed time routine. In the day, when ok do get him to nap, as soon as I put him in his cot he wakes up but if I hold him he can sleep for hours. Please help I'm exhausted and would love it if his dad could settle him at night sometimes so I can get some sleep. He also won't take a dummy!!
