Query: Wonderful Book

This is a great book on baby massage. I started giving my son massage when he was having gas issues. the techniques in this book worked on helping to relieve his gas and get it moving.Now that he is no longer having these issues we have continued using the massage techniques - it calms him and gives us a great bonding experience. I highly recommend this to all new moms!
