We've just been out and spent a small fortune on a toddler bed for my 20 month old son as he seems allergic to his cot and screams at night when he's in it. Also he's getting a bit long for it.
My husband is going to assemble it this afternoon while my son has his last nap in his cot sob 
How do we approach bed time this evening? Should we make a big fuss about his new super fabulous bed, or not mention anything at all, and not make a big deal out of it?
What did you do when transitioning from cot to bed?
