M.L.
I made homemade food so not sure difference between 1st and second store bought foods but I can tell you with my first child I was ever so careful about everything I fed her. Then I had my second child 18 mos after the first and the older child handed everything under the sun to the second one whenever I turned my back. Can you say peanut butter and jelly at 7 mos old? I almost had a panic attack but baby 2 did survive everything tossed her direction by my little helper. Good luck and don't worry too much!
