Is she going to have curly hair?

Her hair is very thin and this is just in the back, rest of her hair is pretty straight (she is 15months). Just wondering if she’s going to have curls or is it just baby hair?

I have very straight hair, so does daddy, so we have no idea how to manage curly hair.

The curls get dry and tangled. Should I be conditioning her hair? With coconut oil?
