My LO has been waking at 4am for a few months now, I have tried letting him cry it out but I have 2 others who have school and don’t want him to wake them (he has the loudest cry). So have been bringing him into our bed but won’t go back to sleep unless I give him a bottle. Most of the time it takes over an hour to get him back to sleep, but it really varies. This is even in our bed, so sometimes we are up from 4am. It’s absolutely killing me. He has a morning nap at 9am for about 45 mins - 1 hour. Then a lunchtime one around 12:30-1 for about 90 minutes/ 2 hours. He then is so tried that we usually give him his bedtime bottle around 6:30pm. We tried giving him a little nap at 4pm so he would last out til 7:30 and he slept til 6am one night and then went back to his usual 4am wake up. It seems it doesn’t matter what time he goes down, he wakes at 4am. He sleeps in a sleepyhead grand in his own room, but think he has got into a routine of waking at this time and can’t self settle. Does anyone have any advice, as we are really struggling, as our other two slept well.
