@Phoenixwings1989, nope no trouble at all with her moving to her own room. The only thing she asked for was a nightlight, which she still has, as she doesn’t like the room to be totally dark. She’s 4 now, no sleep issues at all.
I went through a stage when I googled everything about sleep and thought I must be an awful mother for not sleep training - lots of websites imply that if you don’t do it, your child will never self settle, won’t be getting enough sleep in the meantime which is bad for their development etc etc.... but it just didn’t feel right to me so I didn’t do it and worried like mad I would do my DD harm by not “training” her. Turns out to be complete crap - I suppose if they didn’t say stuff like that, nobody would pay for sleep consultants/books/sleep programmes etc!
I’m not saying you can’t do sleep training. If you want to do it, and that’s what your family needs, then by all means. There are plenty of websites and sleep programme that will take you through different types of gradual withdrawal/controlled crying etc. All I’m saying is that you don’t have to do it if it doesn’t feel right for you. We never did any kind of sleep training because I just never felt like it was the right time. DD goes to sleep perfectly well, I haven’t had to stay with her till she goes to sleep since she’s been in her own room (except the first night), I kiss her goodnight and tuck her in and leave. There have never been any tears, she sleeps through perfectly well (with the exception of a brief patch when she was potty training and used to wake at about 3am for a wee) and wakes happy in the mornings.
If you do sleep train, you’re likely to get more sleep now. It’s a much quicker fix that just waiting for them to naturally develop more adult sleep patterns, so if you need it, go for it. It just never felt right for me and my family. We all have different situations and different needs.
If you end up cosleeping by accident, I’d suggest just planning to do it - much safer and more comfortable for everyone involved! A friend of mine who coslept with both of hers at once stuck a single bed next to their bed to make it wider (not something I had the space for). Depends how much of a star fish your little one is what will be useful to make it a comfortable arrangement! We put the cot next to the bed (with side completely off) and that just gave us a bit more space in total.
One thing you will find - health visitors can have useful information, but they also come with a TONNE of prejudice and strong opinions, much of which isn’t based on anything in particular. They often have opinions on sleep/weaning that’s bear no resemblance whatsoever to up to date research. By all means listen, but be prepared to do a bit of your own research before feeling you have to follow their advice! Also remember that your baby is YOUR baby. Nobody would ever suggest that all adults are the same and have exactly the same needs. Your baby will not have exactly the same needs as every other baby. You know them best and are the best placed to make judgements.
