Why is it that I have the drooliest babies? Tessa soaked through at least 10 bibs a day for I don't know how many months and now Lyla is following in her sister's footsteps. People always say oh she must be teething, but I don't know. Tessa didn't get her first tooth until she was 11 months and the drooling began around 4 months. We'll see with Lyla. She is definitely a drooler!
