To keep dd in our room and ds in his.

[NickyEds]

We have a just-turned two year old ds and a 5.5 month old dd. At the moment ds is in the nursery in a cot and dd is in our room in a crib. Ds is a good sleeper and he loves his cot, he naps for 2-2.5 hours in the afternoon and goes happily to bed at 7.30 until around 6-6.30. Dd goes to bed at 7 ish, I feed her when we go to bed then she'll sleep until 3-4am when she'll have another feed. After this feed she's a bit of a nightmare to get into her crib so come into bed with us. It's not ideal but at least we get some more sleep.
Dp thinks we should move ds into his new big boy room and dd into the nursery. He thinks it will be easier to move ds before the mornings get lighter and thinks dd is less likely to end up in bed with us if she's in the nursery. He also thinks that we're making a rod for our own backs by bringing dd into our bed (he knows someone who's 4 year old still sleeps with them). I'm happy enough to leave ds in his cot and leave dd in with us (although she may have to go into a travel cot). He probably has a point but AIBU to think that this sleeping arrangement isn't that bad considering our dcs ages?

Have you tried putting her in to play? I had my neice when she was a baby and I got her to sleep in her cot by putting her inside with her toys to play (me on the outside). After a few times she'd start getting drowsy and sleep (prior to this she'd only sleep in my arms). It wasn't instant but she was sleeping the night through in her cot after a few weeks.
