Mine all ate weet bix from 6 months. DD2 especially. Still loves it. I actually never heard the over 12 months til I mentioned it in here. By then 2 kids were past that stage & DS was in the middle of it. Weet bix & avocado sandwiches were his main foods when we started solids.

DH was started on weet bix at a very young age too. Didn't hurt him
