Anyone deal with curly hair?

My girls(2y.o) hair is starting to curl. I absolutely LOVE the curls but it's hard to keep them looking not so crazy lol. I use Honest Co shampoo and conditioner. I've never put product in her hair. My hair is pretty straight so idk what to do with curls! I brush her hair often with a soft brush, it'll look pretty for about 2 mins until she sits down.

Any advice? Any toddler friendly products to help it from looking a complete mess?

On another subject... is it absolutely bonkers to let her bangs grow? I usually pin it in a bow.. sometimes itll fall out and her hair will get in front of her eyes, in which case I try fixing asap My in laws keep telling me to cut her bangs but I dont want to go through the endless bang cutting cycle.. just want to let them grow out.
