Okay, you see the seat of the train? It opens and you can put stuff in there. So on many occasions I have made a mental note as I notice Noah stuffing it full of blocks, balls, and whatever else might fit in there. Later, as I pick up toys and put everything away I remember, oh, yes, the train seat, but I open it and it is empty! How does he always fool me? How does he always remember that he packed it full of stuff? And crazy me, I check every time! You would think that I would at least learn! Toddlers are always full of surprises--aren't they wonderful!!!
