I can see where you're bothered by some people answers.
Leah.....seriously!!!
The NEW recommendation by the AAP (american academy of pediatrics) is to start around 4 months. They are NOW discoverying that waiting longer is INCREASING allergies to foods!
My advice to you babysmama is that you follow your mommy's intuition! Rice cereal, will NOT hurt your baby, nor will sweet potatoes, green beans, peas, babanas, applesauce for babies etc. Have you heard of anyone really being allergic to this stuff? NOPE.
She is old enough and will be just fine!!! Go for it. She probably is hungry! I got cereal at 4 weeks old as baby some of my siblings earlier. We are all fine! If there's a known food allergy in your immediate family, hold off on that. Otherwise, go for it!
In the future, if you get nasty response, report them. And on a question like this? Really! Someone must be pms'ing LOL :)
