A little about our sleeping...or lack of

Last Friday night, Lauren started refusing to sleep in her crib. Refusing by screaming and crying until her face was completely wet, eyes swollen and hyperventaling-type breathing was happening. Being the quick thinking parents we are, John suggested getting her new princess tent for her to sleep in and she loved it. Ever since then, she has been sleeping in her room, in her tent, with her crib mattress on the floor of the tent.
Without bars to keep her in place, she has gotten out of bed a few times. Usually, between 2 and 4 a.m. I have successfully gotten her back into her own bed, but I am wiped out the next day since I am used to sleeping all night, or at least having that option.
Tonight, she will have her big girl bed to sleep in. We are going to Sam's this morning to buy it. I hope she likes it and stays in it.
Sleep is good.
How old do you have to be before you realize this??
