Hmmm its a tricky one, my lo sounds similar, he wakes every 1.5 hours which is tough but even when he is asleep, he grizzles non stop, cries out and is generally just very noisy!
Hubby wants to put him in his room which is only next door but I've been saying we shouldn't.
I would maybe speak to your HV next time you see her, personally I'm going to wait until the 6 week appt to ask mine but hopefully I will hold out until LO is 3 months old before moving him.
I had mentioned it to MW a couple of weeks ago about all the noises and she said its common at this age for them to be noisy during the night, so hopefully they will settle down soon!
I don't think that there is anything wrong with putting your lo in his own room early, but I would just wonder if you will end up going into check on him countless times anyway or lying in bed worrying. This is one of my concerns, although my other concern is that I'm so bloody knackered that I won't wake to check on him and then something might happen....I don't think you can win either way!
Sorry that's probably not very helpful!!!
Can you get any sleep during the day or when hubby is back from work?
