For my children's hair, I use Herbal Essence Intense hydration. I know that might sound like it is too strong for young children, but having thick, afro hair that is in constant need of hydration, it works really well, as does their intense conditioner.
For bath, I am still trying to formulate my own home-made wash. I use Infacare in the mean time, although in the past, before LO was mobile, I would use just plain water. I use my own mix of sweet almond oil and coconut oil as a moisturizer. They have very sensitive skin so I have to be careful what I use. Its all very trial and error, so perhaps you just have to investigate and see what works for you. x
