Share Room

I am always battling myself as to whether I made the right decision to have my girls share a room or not. They are very close together in age and I want them to grow up very close. I hope they learn to be best friends through life but I do not want it to be a decision that was forced on them. Now that they are both ready to move out of their toddler beds I am pondering if I should get them bunk beds or try to convert a room in the house and split them up. The beds are a great solution to our space problem but I want to do what is right for the girls.
