K has been a drooler from pretty early on, I'd say at least 2 months? Well, she must be officially be teething now, because her drooling could compete with a St. Bernard! lol! Add that with spit-up, I think we go through 4 bibs a day easily! More if the grandmas are over and want to constantly change her bibs.
How many bibs does/did your LO go thru in a day? We have probably ~15 bibs in rotation and I'm on the verge of buying more. How long did you use bibs for?
