[|Human|] our 4 month old son, who is exclusively breast fed, we think is starting to teeth.  Recently we saw a little bit of blood in his spit up, and today his spit up had brown in it.  He is otherwise happy, not fussing, no fever, and eating normally.  Is this just from the teething or should we take him in to be checked for anything else?
[|AI|]  Thanks for your query, I have gone through your query. The bleeding from the mouth can be because of the teething, when the teeth erupt it penetrates the mucosa and can result in bleeding. The other possible cause can be a cut in the oral mucosa. Better to consult an oral physician and get it ruled out. If it is secondary to teethe or a cut, it will reduce in one or two days. After consulting an oral physician you can take topical anti-inflammatory Chat Doctor. I hope my answer will help you, take care.
