Room sharing nightmare!

Pen • 8/17 🌈👧🏼 | 11/19 🌈👦🏼| 👨‍👩‍👧‍👦

My almost 3 year old is a terror to my 8 month old so much lately at bedtime! For the most part she always left him alone and goofed off on her own until she went to sleep, but the past couple days she just won't behave at bedtime! They share a room, he's in a crib and she's in a toddler bed. She'll go over to his crib and steal his pacifier, steal his comfort animal, or even get into his crib and bother him. She will do this even if he's asleep, which wakes him up and then of course he cries!

Any suggestions, short of their own rooms? (Not really an option, we only have one bedroom for all of us!)

Tonight we ended up putting the baby in the pack n play in my office, but that's not sustainable either!
