Curly Haired baby!

Hey guys my almost 6 month old has curly hair and I’m not quite sure how to take care of it. When she was born it was very soft and moisturized, but it’s starting to get dry, frizzy and the curls are dull. It’s not to bad yet, but In person I can tell that it beginning to happen and would like to stop it from getting bad. I don’t have curly hair and no one in my family does either besides my mom and my sister and they don’t know what to do. With that being said I’m coming to guys for any suggestions! I would really appreciate it. I just want my baby’s hair to look and feel nice so that as she gets older she loves her natural hair. The pictures don’t show what I’m talking about very well, but they do show you guys her curl type. Thank you for and suggestion!
