Hi, FT. Agree with the others and you that the safety of your toddler comes first.
You hold the cards here.
If he wants to see his daughter, he has to demonstrate that he is sober.
To demonstrate that he is sober is to take a breathalyzer test.
That he agreed to, btw.
His pushing back against this is classic addict stuff: prod at your boundaries until he finds a weak spot.
Stay as strong as you have been heretofore.
Your daighter comes before him.
Peace.
