Hi !! Your daughters are beatiful , you should buy a really mild shampoo ,better if its is for curly hair , second a conditioner with emolients and I dont think you need a cream ; but leave-in would be great !!
Also , because your daughters dont have to much hair , use your fingers smooth when they have conditioner (ONLY) detangle whit conditioner .
I hope this works , its really easy to stle curly hair in kids , Im still try to figure out my hair , because nobody helps me . Im 17 , so you are really good mom.
