I started using aquaphor on our LO for his dry skin and it works really well. He also had baby acne and it helped it also. Does go on slightly greasy but absorbs fast.
I would try something called CapriClear. It's an all natural moisturizer that is specifically formulated for dry skin. It will help relieve the itch, if he is and will certainly help with the dry skin. My whole family uses it and we love it.
