I can't believe anyone would tell you to start feeding your baby solids at only 3 months. That's crazy! Maybe 20 or 30 years ago, when parents were poorly educated, and pediatricians were no better! I wouldn't even consider feeding anything from a jar to your baby until after 5 months, preferably after 6. I started my son on homemade solids between 6 and 7 months, and realized he really wasn't ready, so I held off again till around 7.5 months, when he had a few teeth, and could easly accept and swallow mushy fruit and veggies. Even then, he was really only eating them in place of maybe 2 nursings, the equivilent of maybe 2-3 or so ounces a day. They work their way up from there, but you really have to start slow with foods like that. Also, if you're still nursing, you can add your own breastmilk to the mixture, so it's more liquidy and easier for your baby to digest, since starting new foods may be constipating. Good luck!
