What if She Drops Him???

I came down stairs this morning and Tayden (who is very protective of his little brother, Trevyn) and I had this conversation:

Tay: Mom, is Kaylee allowed to hold Trevyn?

Mom: Yes, she's big enough.

Tay: But what if she carries him around?

Mom: Well.. she probably shouldn't too much, but she's okay if she's careful.

Tay: But what if this happens? (then he shows my the picture he drew)
