Anyone had a toddler with MRSA? Any advice?

So my toddler has been getting recurrent boils for over a year now. Her doctor told me to give her bleach baths and put ointment in her nose and on the sore. she's been on antibiotics for the boils 4-5 times now and it makes me upset because IDK why she keeps getting it. Her grandma had her on the weekend and I told her she had a boil on her butt and she ended up taking her to urgent care because my daughter was crying because it was causing her pain. The doctor at the urgent Care took cultures and they said it is MRSA. I live with my godmom and my siblings there's 10 of us at home so I told her grandma to keep her for the rest of this week for me just to give antibiotics time to kick in. I don't want anyone to catch it . . I don't want her to keep going through this. Any advice from Mom's that have gone through this? Her grandma said it could be from her not finishing her shots but she's only 2..
