Okay, I know the transition to a twin bed is and should depend on the child, but since DH and I are having a disagreement on this, I thought I would ask around anyway.
DH thinks 3 is too young. I am taking into account the upcoming need of a second toddler bed for one of my mow 20m old twins. I think having 3 toddler beds would be a silly waste of money, since I won't need 3 at the same time again (I hope!!!!!) and I already have 2. He thinks it is unnecessarily taking up space in the room that we don't have, and is pushing my daughter unnecessarily.
I also thought that transitioning out of nighttime diapers and into a "big-girl" bed at the same time would be a great idea.
