Peter gets his chance to stay in the toddler room

So as I was told by the director. With more young babies coming in his class, Peter was found to get bored sometimes. Though he is still too young for toddler room, the director said that they would let him stay with the toddlers for some time when there's low attendence in the toddler room if I agree. Why will I reject? This boy is getting big and we need to keep him busy and curious to avoid trouble, right?
