I wouldn't worry...I have 3 boys, and the first one was colicky and VERY gassy. Well I learned that gentle patting is just not effective to relieve gas, and now I have a 2 month old gassy newborn, so I pat his back pretty firmly. Even visitors are afraid to pat him firmly when he gets upset...but it's not relieving to my baby if you don't pat firmly enough. Another thing that works for me is to lie your baby tummy down on either a sofa or on your knees,and pat/rub his back fairly firmly. Actually the nurse in the OB unit taught me this, and it works very well for my 2 month old. Our oldest stopped being gassy around 4 months old, so I'm hoping our 2 month old gets better, too. It can really be frustrating.. :)
