He uses a dummy and that's all he wants when he wakes but I don't have the energy to work out how to take it off him.
Why do you want to take the dummy off him if it is all he wants to get to sleep?
Getting rid of the dummy completely is a worry for way in the future, when you are not sleep deprived. Not a worry for now.
I don't move my DC into their own room until they are able to put their own dummy in. Up to that point, much easier to have baby in cot next to me and just reach across to put the dummy back in if needed.
(I only usually need do this once in the night with my September born DD).
The better and quicker baby settles with the dummy, the deeper their sleep and over time they should only need the dummy when first going to sleep, not through the night.
Septbaby - Wise words for serenity? Just know you are not alone - I'd guess at well over 90% of first born children having sleep difficulties (and still many second and third borns). Just about all parents go through it, they really do.
How about trying the 5 minute rule to start teaching self-settling? Give baby 5 minutes to try and settle themselves before you go to him.
Also consider the dummy debate. Babies brains are (apparently) not ready to self sooth without any prop until well after the pre-school age. So decide for yourself if you are willing to wait 3 or 4 years for the baby to naturally self settle. Or work hard to introduce a sleep prop before then.
