My 4 month old goes down really well at the beginning of the night, with a dummy. He doesn't need any input from us once he's been put down now to get to sleep and we now leave the room so he's definitely not relying on our presence to get back to sleep. He's been waking up every 1-2 hours at night, often for the dummy (which I know is part of why he's waking up) but last night he woke up crying a few times with it still in. We've tried to get rid of the dummy but it didn't help, he still woke up crying every 1-2 hours during the night but took longer to get back to sleep (we did it for about a week so I would have thought he'd at least start to get used to it by then...). He also takes a long time to settle sometimes - last night we offered milk when he did but he only had about half of his usual amount so he didn't seem to be that hungry.
During the day he has a nap around every 2 hours, for either 45 minutes or an hour + a half, with his last nap being at around 4-5 before bed at 7...
Any advice would be much appreciated!
