Too much wind...

Is your little one breast fed or on formula?  I ask because some kids have difficulty processing some of the additives in the formula.  Both of my kids were on formula and had difficult with the high iron content in the powdered form.  We had to switch to the

concentrated (which is more expensive of course!) for both.  Once we did, the gas and tummy aches subsided.

Another tip would be to try this massage technique:  1) Lay your baby on his back.  2) Starting in the middle of his chest with both hands move up and around his chest and then down towards his stomach making the shape of a heart (wish I could draw a picture to demonstrate).   3) Use gentle strokes and repeat several times.  This technique is said to help with digestion. 

Of course, I would discuss the concern with your pediatrician first.  Good luck!
