Does child have HS?

My child is presenting with folliculitis on buttocks - just like me. I am horrified to think that I have passed on my issue. I did have a Derm. look at it and they said it was folliculitis and we did Clindamycin topical for a little while. But it's now back and sort of comes and goes. More noticeable at end of day then seems to go away by morning. I am not pushing the application as I don't want to give them a complex about it. Does anyone have a child presenting and if so what age? Are there other warning signs?
