Nice bib BUT the sizing is incorrect

I bought these bibs for my grandson because the price seemed fair & I liked the idea of the plastic "sandwiched" in between the 2 cloth's. The quality is nice but the sizing is incorrect. My grandson is only 5 months old,(average in size) & the bibs are supposed to be for the ages of 6 to 12 months but he is outgrowing the bibs already! Doesn't seem fair that "Green Sprouts" isn't advertising everything correctly. So be leery of ordering these bibs because they are for a size NB to 4 months of age.
