Blood on his bib

Brenda • 24. Married my ride or die. 3 children: James, Eliana and baby boy on the way. All 3 under 3. My life may be chaos but wouldn’t have it any other way .
Do some babies bleed why they're teething? I had him on tummy time and I notice he was drooling a lot about so I wiped his mouth and some blood came from his gums I guess..
