no longer want to co sleep - move dd to crib or bed?

[Turquoisehat]

We are finally coming to the end of our sleeping as dd2 now sleeps through the night at 14 months.
We are also moving to a new house next week and am thinking about having dd1 (7) and her share a room - and have them sleep together a double mattress on the floor. This is what dd1 wants.
I don't think dd2 is big enough to be in a bed by herself, but she has never gone in a crib before and has always screams when she goes into a play yard. I was given a crib, I just need to buy a mattress, but I wonder if it is worth it.
Can anyone see any other options - or suggestions? Thanks so much!

We went from co-sleeping to a mattress on the floor at about the same age. I think it is very hard to get a child to accept a cot if they haven't slept in one from a young age. The mattress on the floor makes it easy to settle her down and re-settle during the night. She might get up to come and find you though!

That is a good point, I don't think she would willingly go into the cot. And I guess I could use a baby gate on her door. thanks.
