Curls

So my boy who is almost 13 months have curly hair.

So I’m not sure should I be putting oils or something in his hair.

My in laws had curly hair when they were younger.Now only husband sister have wavy hair.They are older so hair care wasn’t that much their priority.Amd SIL usually straighten her hair.

It’s not crazy curly but he have cute curls I would like to keep them as long possible

And they are on the back of head and his hair is little curly on front but not as much
