My first was the same. I literally go through a new bib every 15 minutes. My Carter's ones are getting long in the tooth, can anyone rec a good bib for super soakers? Or have any advice on how to decrease the neck/under the chin redness?
My sister had this issue with her son and went with plastic bibs that she could wipe off and wouldn't hold the wetness instead of cloth.
Also, have you brought it up with your pediatrician? My sister ended up needing to introduce a pacifier late in the game in order to build up his mouth muscles so that he could control the drooling. That lack of muscle tone also led to him being a late and very unclear talker.
