hi K.,
we had 2 kids in a 2 bedroom home for a while, and it IS tight! i sympathize. keeping her with you longer is an option if you really want it, but please don't feel pressured to do so if it's something you're ready to end. the family bed is a great thing, but it's not for everyone and that's okay. having kids in their own rooms and regular bedtimes is not abdication of parenting, it's just a routine that when done right, is comforting for everyone.
there's often a bit of disruption when you change things, so don't let a few chaotic nights make you feel as if you're doing something wrong. the kids might wake each other a few times, and you might have to go in and rub a back or replace a paci. but if you keep it low-key and resign yourself to a few times of getting up while everyone adjusts, i'm betting that in a week or two everyone will be just fine.
it's also unlikely that a 'shared' stuffed animal or two will be a problem. don't make a big deal over it, just thank him for his sweet gesture and remind him that baby only plays with these toys when she's awake and with mommy.
good luck!
