Six weeks is definitely too young for taking even a bit of solid foods in. I heard of people trying that with 3 month-olds when I was nursing, and that was wrong. 6 weeks is just ridiculous!

It seems that people forget that a baby's digestive system isn't fully mature at birth. It takes time for the baby to be able to handle cereal. Breastfed babies handle digestion much more easily and quickly than formula fed. Formula fed babies have harder bm's and it can make them gassy. Adding solid foods only intensifies those results...equaling some real fussy times as it hurts to pass gas or milk.

I'd advise you to mention this to the pediatrician, and hopefully they can help your DIL look at the issue in a new light (rather than become defensive). (((hugs))) to that little baby ~ the pain and anguish in those eyes is hard to forget! Best wishes to you and your family!
