And do they use moisturiser/SPF? I've been taking mire care of my skin recently and its paying off. It started me thinking about my 2 DC, ages 4 and 5. They have a wash in the morning, bath at night (most nights) . We don't have a shower. So in the morning they use a face cloth and water. At night, the same but probably more soapy as they are in the bath. I remember as a child using imperial leather soap 
I've also just seen on a skincare FB group, discussion about children wearing facial SPF daily all year round. One of my DC reacts badly to list sunscreen so rarely wears it on his face even in summer, just has a very good coverage sun hat, hes never burnt.
Is it really necessary? Year round?
