Peter got 4 new sets of LEGOS for his birthday. He's woken up in the middle of the night 2 of the last 3 nights to work on his legos. And it occupies him for hours after his normal 6am wake up time each morning. He gets distracted b/t following the directions to put them together and then pretending with the new guys in the set.... these new sets introduce knights into his collections.... very exciting. Who knows if he knows which set is which? Once again, I relinquish control here and delegate that decision to Mike and Peter.
