We have 4 children and a 3 bedroom house (baby no. 4 was a surprise). The children's rooms aren't very big. For the older two they have bunk beds and plenty of space but the younger children's bedroom is even smaller. It is currently my almost 3 year old's room but our youngest is one and right now in with us but I feel she is ready to go in with the toddler (and we are ready to have our room to ourselves finally as well). They're obviously too small for bunk beds right now so I'm trying to decide whether or not I should get them a double floor bed to share or get another toddler bed, although leaving a gap between them will mean minimal floor space in the room.
What have others done? Are there any options I'm not thinking of?
