Hi, L.. Yes, yes, yes- start pushing your ex-sister in law to take her to the specialist. If I was you, I would call the specialist myself and see what it could be. I know there are such things as venereal warts, but I do not know if children can get them. Maybe passing through the birth canal? I don't know and have no medical knowledge, but I would strongly suggest getting help for your neice. If your day care lady is watching your neice and your daughters, then I would have her mention seeing them to the mom also, strongly suggesting that she be taken to the doctor before she returns, to make sure it is not contagious. I am worried that these sores might be hurting her, too. Do they seem to bother her? I am a very strong advocate for children, and I say she needs to take her daughter to the specialist or she should be reported to family services. This could be very harmful to your neice. It makes me really sad that her mother is not doing anything about this. I think if you are willing, take her to the specialist when you have her for a few days and see what they say. I would tell her you are going to do it, though, and ask her why she is not investigting the problem. If it is a financial issue, then that is not a good enough excuse in my mind. When it comes to a child's health, there is not a good enough excuse. I hope and pray for you when making this decision, as it is not an easy one to make. Good Luck and God Bless.
