Need Help Please

The other day, my little 7 year old girl just got home from school and told me that some of the the kids at school keeped Teasing her and asking her, "if your dad has female or male gear below" (watered down Words of course).
I told her just ignore it all and if you have problems just let me know again.
untill recently they had presumed i was her mother,so i just found out.hence no issues.

So here is just a small bit about me.
Im TS im living as a female but using my male and female names, this has started creating some issues,but i have pleanty of problems anyway,ive been married for 16 years,have 3 kids One is 18 One is 7 and a baby at 2 Years they call me dad and im ok with that.Im out 24/7 on HRT been on that for 1 Year and am a refrigeration engineer.

The Question

So I would just want to know what would you sugest i should do

Thanks
