We have had Brystal's big girl bed in her room now for about a month so she can sit on it and get used to it being in her room. Today I tried to put her down for a nap in it just to see what would happen, and if she did well, we'll move the crib out of her room. So see for yourself.
I think she'll adjust well, but I will keep you all posted on what happens. She is still asleep now, and this is only day one of the bed.
