I've always used Aveeno Baby lotion. My ds was post-term and was born with cracks in all of his creases. The Aveeno really seemed to help. I've also found that it works really well for me when my hands get dry and cracked from too much handwashing. Other lotions sting, but not the Aveeno Baby. It is also fragrance free, which probably helps it be less irritating (plus, I just don't like fragrance in everything).
So it gets a thumbs up from me
