DS is 3 months old and we already have a bassinet, rock n play and a swing. with DD i never got a pack n play because space was an issue. anytime we travelled we used the rocln play or coslept. with DS I dont want to cosleep ever because it was a hard habit to break so we are always avoiding overnight stays away from home because sleep arrangements are tricky. I dont like to use the rock n play for overnight sleep. if you have a pack n play was it worth it? is it convenient to travel with? if so please recommend one!
