have a 23 month old DS and 5 month DD. Currently DD is in a cot attached to our bed but the idea was to move them in together but... DD doesn't sleep through and I'm worried about things like DS throwing toys onto her face....I guess we wait?
Personally, I would wait. It's horrible to be woken up every night by a baby, and it seems a rotten thing to do to a 23 month old. That said, he may sleep through it all, it depends on the child. Ans I understand your concerns about a toy on the face - 5 months is still too young for the baby to be able to reliably get rid of a toy. Do you have the space in your room to detach the cot from the bed as a start in the right direction? Even curtain an area off? I babysat for one family once who lacked a bedroom for the baby, and the other kids were teens, so really didn't want to share. She had an odd shaped hall and had curtained part of this off for the baby - worked surprisingly well!
I have an 11 month gap between my 2 boys and moved them into the same room when the youngest was about 7/8 months old He was a bad sleeper and I worried about him waking the eldest but amazingly the eldest mostly sleeps through his tears unless they're hysterical - and then when I go in he'll tell me the baby is crying then lie down and go back to sleep
You could always trial them and if there's too much disruption move the bub out again
We loved getting our room back to ourselves with no more tip toeing!
