So my sister and kids said they would use preventive lice treatment since my son and I got lice. Yet my niece admitted to lying about using it to grandma. That’s fine. If you don’t wanna use it don’t lie. But I’m about to have my new baby Monday and I don’t want to be reinfested by them since we got it from them in the first place. My sister is determined to hold my baby. They are my neighbors. I offered to pay for over the counter treatments and get their head checks cuz I swear I see lice eggs on one of them and my sister disagrees. She said she will go and take the kids to the salon to get heads checked....but it sounds like she doesn’t want me thete. Given her track record for lying I’m not going to trust her word. I don’t see any treatments that say you can place a pesticide on a newborn...I’m trying to not cause I fight I love them but I don’t want them holding my baby without being 100% they don’t have them anymore. Any suggestions?
