Curly hair tips?

My sons hair is just starting to grow back in and it’s already out of control 😂 any blogs or tips for curly haired mixed kiddos? I can’t believe how much his hair has changed since birth lol

Started dark brown and straight

Went bald and now coming in this light reddish brown curliness 😂

I’m so excited for curls but obviously want them to look nice too lol. My own hair is stick straight and dads hair is very textured so this is new territory for both of us lol
