sleeping in a pack n play??

So my 8 month old is sleeping in the pack n play right now and indefinitely. My husband is over co sleeping because she's getting so big and he can't stretch out. Frankly I'd rather kick him out! ;p so we don't have a crib we have a pack n play. It's really hard so I stuffed a cushion between the sheet and the board. I hope it's ok for her I feel bad :/. Someone tell me their baby sleeps in a pack n play. Oh she's a belly sleeper too. Gah I feel bad, I want her back in my bed!
