When did you start feeding baby food?

If you've found a great deal, then go for it! I started my son on cereal at 4 months and he hated rice, sorta liked oatmeal, but went straight for the squash and sweet potatoes like nobody's business. I always mixed in baby oatmeal to give it more depth and texture and to fortify his iron intake. All babies will respond to spoon feeding differently, so just try, then try again and give your little one time to adjust on his/her own schedule. It's SO much fun at this age.
