Kailie likes to put her hand into her mouth

Kailie likes to put her hand into her mouth. Her brother, Yuta, also did the same thing when he was a baby at Kailie's age. Mommy still has Yuta's picture chewing his fist. But Kailie is usally putting her fingers to her mouth, not her fist. Since her fingers are long, sometimes she choked herself with her fingers. When it was Yuta's time, this sucking hand thing did not last long because mommy always tries to take his hand away from his mouth. But with Kailie, since mommy is pretty busy taking care of her hyperactive brother, sometimes mommy forgets to take Kailie's hand from her mouth. Hopefully this thing will pass soon, and mommy really does not want this to be Kailie's habit.
