I know this is going to sound gross and even weird. I was recently diagnosed with trich. My concern is about my 4 year. I caught her playing with a previously used cardboard tampon applicator that I had on top of the trash(i usually let her play with paper towel and tissue rollers before throwing them away). She had it in her mouth blowing air through it. Im afraid that she could contract trich that way. What should I do?
