Baby's bad breath....ㅡㅡ@

Ah... elementary school kid's morning breath after waking up...

So, I often see oral probiotics on TV broadcasts, so I buy and take them..

Sometimes I have bad breath, and sometimes I don't.

When I was born, my breath really smelled bad...@.,@

Why is that... The dentist said that the cavity is very minor and can be treated later.
