Here are some more meanings of a dream about a baby biting you.
There is something that you are underestimating
If you see a baby bite you in the dream, it could mean that there is a problem that you are underestimating. It could also be about a habit that you think you can keep under control but that might get out of hand. This problem could be in your relationship, your education, your career, etc.
There could be a bad friend in your life
If you see a baby bite you, it could mean there is a bad friend within your life. This is someone that might not even be aware of their negativity toward you but might still harm you in one way or another. You might want to scan your life and see if there is anyone that fits this dream interpretation.
Dream about a baby biting your finger
A dream in which you see a baby bite your finger means you might soon experience a small problem that will make it hard for you to be productive. While the problem will be a small one, it might set off a domino effect and should therefore be handled carefully.
Dream about a baby biting your ear
A dream in which you see a baby bite your ear means that you might soon have rumors about you get spread by someone you would never expect. The rumors, however, will be trivial and will harm neither your reputation nor your friendship. You will treat them as a joke.
