Big girl bed

I decided to transform Brynlees crib into the toddler bed she had been requesting to sleep on the floor every night for a week and I am tired of lifting her out of bed soooo..... Hello big girl bed! The first night she tricked us and slept right through the night and then the last few night she has asked to sleep on the floor so we let her think she is going to sleep on the floor but put her in bed before we go to bed. This has worked a few times but last night she was crying and I was to tired to get out of bed but her cry became more desperate so I went in and could not find her. She had rolled out of bed and under Maddisons bed and could not get out. Poor peanut was trapped so I grabbed her legs pulled her out and put her back on bed and she had no problems the rest of the night!
