Nursery rhymes that toddlers will relate to

Hector Protector was dressed all in green;
Hector Protector was sent to the Queen . . .

Hector is an obliging dog who lets his toddler friend clothe him in jacket, scarf, and sock. On the boy and dog's visiting rounds, however, the Queen (mom) and King (dad) are not terribly receptive when Hector jumps all over them. "So Hector Protector was sent back again" -- for a nap with his friend on the floor.
