Bibs Why does my baby dribble so much? The salivary glands start to work at around 2–3 months. However, at this age, your baby still hasn’t mastered swallowing. When he/she starts teething, you can expect even more dribble! During the day, opt for bandana bibs, more fashionable. See above: NOBODINOZ“Candy Secrets” Oeko-Tex® organic cotton bib 194
