No Idea What To Do Next

Lisigp60 my sister in Tennessee is a retired children's services officer and she has verified that your son has every reason to refuse contact between the girls and their mother.
Your 11 year old gd is old enough to be interviewed and her views taken in to account. Police really should not be arresting their father given the serious reasons for stopping contact.
Hope this helps.

Oh agnurse, you do keep on doing that, don't you? Please do try and remember that the laws in Canada are not the same as in the UK. And you have been reminded before.

Lisigp60.....A good point has been made, advice is dependant on which country you live in.

Did you get any support from the Police when you went to talk to them?

Thinking of you all

agnurse not only provides information that is often legally inaccurate, it usually is totally lacking in emotional intelligence or compassion.

If your DiL was with your son for 10 years and became addicted to ice within that time whilst also being mother to his 2 children, how and where was she introduced to the stuff and why did your son not notice it/ know about it?
It seems strange that an addiction to a class A drug could go unnoticed.

Gabriella it seems that mum became addicted to ice after the breakup, when she met her new abusive partner.

Another thought. Your granddaughter's new baby sister is most at risk if her early life is chaotic and abusive. The addicted partner is her father so she doesn't even have the wonderful support of your son. For the sake of that little one who is living daily with those two, I would invite you to approach Social Services without delay. Otherwise your granddaughters will feel responsibility for her beyond their years.

Sorry, just seen your reply dated 29th. Do hope your visit to the police was successful and I hope this awful situation is soon resolved for you and your husband. Deep empathy to you both.
