My kids get pretty obsessed with certain toys.
Kyson's obsession isn't really a toy but it's his blanket. It was the blanket that went with the crib set when he was about 1 and sleeps with it about every night since. He is really into beyblades right now and has this little car he says is his favorite.
Adalyn LOVES LOVES LOVES Cinderella, or "Lella" At her birthday party she squealed when she got a Cinderella. She's also really into dress-up and loves to be Cinderella or Snow White. Belle is probably another favorite, only because Belle's dress is yellow and Adalyn LOVES yellow.
