For the at least a month now ds has been impossible to settle back to sleep ater waking for a feed at about 4am. He feeds until about 4.40, at which point he usually ( and rather loudly) fills his nappy. He then wiggles and chats for about 20 mins. I then consider 'getting up' at about 5am. He will eventually settle back to sleep at about 7am when we return to bed. We co-sleep, so I am aware of disturbing DP, but more than half the time we sleep in different beds anyway (when he is working) and the pattern is no different. I try to stay in bed and keep things dark and quiet and only nappy-change if necesarry. I have also tried more feeding and rocking to induce sleep to no avail. Does anyone have any tips on extending the sleep? I do have a lot of patience, but effectively getting up at 4am cannot continue. Baby is 7 months old, goes to bed any time between 6 and 7pm.
