I started my 8th month old daughter on purple fleshed sweet potato today and only just realised that the recommended age is 12th month! Am i doing something wrong?? Btw, she ate them all though..

As long ur baby show no reaction to allergies, and constipation, she is fine. The recommendations is just a guidelines. Some kids can't adapt to the food too early, my son have sotong when he is only 10 months+ and he is fine with it, as seafood has higher allergies risk just like egg. Some kids only ok with eggs after 1 year old at later stage.
