Initially, when we moved Luke and Sarah into big-kid beds, Jake seemed really content with staying in his crib. We thought he would just stay there for awhile. After a week or so, he started to show interest in the others' beds. He was getting frustrated with his lack of freedom. So we decided it was time to open up his bed too. He loves it! Although now with three mobile toddlers there has been even less sleep and more play during nap time. We've also seen an increase in the numbers of fights and bite marks. So now the question is "do we keep them together or put them in separate rooms"?
