what is the best thing for gases??

We used Oval for my son when he was a newborn.  It worked quite well.  Also, my husband and in-laws taught me to hold him like a monkey.  You lay him/her on your forearm on his stomach with his/her legs and arms hanging down.  My son often fell asleep that way.  If you're breastfeeding, you should watch what you're eating, ie.) spicy foods, dairy products.  If something makes you gassy, it might do the same for your baby.
