My son will be sharing a room with his sister after a period of time, but they will have limited space in their room. My daughter is currently in a convertible toddler bed. My two options are either giving the new baby the crib and getting my daughter a true toddler bed, or getting a mini crib for the period of time that the baby will need to be in a crib. My game plan is to reassess and possibly move them to bunk beds when he is 2ish. I'm not 100% sure, but I was thinking the mini crib might save space until it's time for a bunk. Thoughts?
