Miss Peach is just over two and half years old. The discussion has come around to a big girl bed. The Little man is one and a half, he is still sleeping in a mini crib. He needs to be upgraded to a regular crib...now! Here is my dilemma...How will I ever get my baby girl to sleep if I can't contain her in a crib? My options are: buy a big girl bed for Miss Peach and let The Little Man have her crib, or buy The Little Man his own crib. I just don't know what to do. At what age do you start sleeping a toddler in a big bed? Miss Peach totally needs to be caged in order to go to sleep. She will sleep, but if she has an option to get out, she will. I am in new territory here. Who has gone through this, and how do you do it?
