He has always had a drug problem, but the conviction came after the children were born.
Does he use his parenting time? In my opinion he doesn't. Often he will take the children to his mother or sister. Often he sleeps and leaves the children unattended. The children always come home dirty and often with the same clothes that they wore when they left. He allows them to stay up all night and watch television and we have concerns that they aren't eating properly when in his care.
I have no reason to suspect physical abuse, but I'm not 100% sure that there isn't some sexual abuse happening. In my opinion the children suffer from metal abuse because of the way they act when they return home. The oldest (7) is has now started not wanting to go to her fathers.
My son and daughter-in-law have provided an excellent home for these children. They are well-cared for and provided the things they need. I keep telling my son to keeping doing the right thing and the children will respect you for it.
But, it is getting so aggravating what I see them going through.
So, your daughter-in-law HAD children with the father even though she KNEW he had drug problems? She chose this person to be the father of her children.
As for children staying up late, etc? That is what we call parenting differences.
If you have reason to suspect sexual abuse, then your DAUGHTER-IN-LAW needs to take them to the doctor. If there is anything, the doctor is a mandated reporter to CPS.
As for the rest of it, highly suggested that you stay out of it.
