Please can someone help me with my mixed baby

That picture is literally my baby girls hair. I’m Zambian.
I use a kids tangle teaser, nalas baby leave in and blue magic. Basically I shampoo her hair twice a week to avoid drying it and detangle before that, after her bath I use blue magic. And then to style I detangle/ wet her hair, add the leave in and finger rake it.
I have tried to do cornrows and because she’s 9m, it actually doesn’t last 😅 but she’ll definitely be getting braids in the future, just gentle ones.

I don’t think a wave cap is what you want, maybe a satin one? And an evening hair routine.
Hope that was useful it’s hard typing it all out!

Thank you we have some blue magic too here at home I know how to cater to his hair but I don’t know how to stop the tangles it constantly needs moisture aw cute yeah my sons hairs the same as your daughters by the sound of it thanks for that he just hates brushing his hair it hurts him! X

Look up Christina's Curls. She has products designed specifically for babies and toddlers with curly hair

You may need different products. It sounds like you have the detangling down but what type of brush are you using? Sometimes those can cause damage. What type of shampoo? If you're using a lot of products, he'll need clarifying at least every week. I like shea moisture coconut & hibiscus Kids line.

Your son's hair is losing moisture. I don't have enough info to tell if it's high porosity or low porosity hair. But you need to seal in moisture either with the LOC method or LCO method.

If your son's hair is easily saturated and seems to get dry very quickly, then it may be high porosity and you would use the LOC method -Leave-in, Oil, then Cream (curl cream or styling cream). I recommend avocado oil, jojoba oil or argon(Moroccan) oil. They are light and penetrating. Do not use raw coconut oil in the cold weather for daytime wear.

Definitely get him silk sheet and pillow cases if he's in a bed. Wouldn't recommend professional braiding now but you could look up flat twists for sleep.

You can detangle it while it’s wet and has conditioner in it, so it won’t hurt. If you wash his hair and use conditioner after it will help and sometimes you don’t need to use shampoo at all. When he gets out of the bath, you can put leave in conditioner, oil, and whatever product you normally use. The oil should help lock in moisture. You might want to try a new product. Curls are all very different and maybe the product is drying it out or maybe it used to work well but his hair is changing and now he needs something new. Personally, I have to change my own products every few months. I use SheaMoisture Kids Curling Styling Cream for my baby and it seems to work well. Also, using a bonnet at night or satin pillowcase will keep his hair from drying out.

Update thanks girls I basically am in the uk I use curl define by cantu and for shampoo and conditioner I use only curls or my little coco after baths I sometimes put on aloe Vera then in morning I use castor oil sometimes or avocado oil with a spray bottle and wet it first it’s a patch of dryness at the back of his head like where the pram has rubbed and dried it out this is today as you can see the curls look amazing but then you have this huge dry patch that actually gets dry constantly and knots even at sleep times and to brush it out it’s all tangled I’ll attach images down bellow thank you all too ladies some great information xx

Ps to add I’m not ashamed to admit I am a white woman I am trying my best with his curls I have naturally curly hair but his is different and I want to be able to give him the right stuff that he needs thank you for all your advice
