I don't think skincare for children is a must before my children's skin get so dry and sensitive. I have tried a lot of skincare for children until i found the right one for my child. Here is my recommendations for your kids.

Here is only hair & body wash recommendation. You should choose one that does not have sulfates and parabens. One thing you should remember is that when your child takes a bath, do not use warm water and dry immediately after bathing. Just tap the towel.
I have tried this one when my son's skin was dry and itchy. I brought him to the doctor and the doctor told me to buy this one. And the result is very good. My son's skin is slowly improving with extra care.

This step can not be missed! Right after take a bath and tap only with towel, use body lotion directly. It will help keep your child's skin moist. But still, choose paraben and sulfate free!
