In a way yes I mean you are only doing what is best for your little girl but if the mother would like your daughter and the boyfriend to bond then you have to give it a chance. Do what ever feels right inside and trust the people who are coming into your daughters life. Its normal to feel uneasy and you could talk to your daughters mother about the situation and see if they can cut down the drinking. Whichever way trust yourself:)
If she is young then yes but on the other hand it's none of ur business. The mom has Rights just like u do n u shouldnt be getting in her business about whether her bf is good or not. I suggest asking ur daughter if she likes the guy or not and If not then tell the wife that, but she likes the guy explain to her that drinking should not be done on a regular basis
Make sure your daughter NEVER gets in a car with them. Maybe set a condition that they only see her during the day, when they are sober, or without the boyfriend. If you try to prevent her from seeing her mom altogether, you can end up in court. Don't be afraid of that if you really think she is in danger though. Your child is priority #1, no matter what anyone thinks about you!
that is right, if they drink excessively, and your daughter is around them often, she will begin to feel that drinking high quantities is normal and that it is ok. i do not know your daughters age, but if she still lives with you, you have the right to denie her mother the right to see her daughter because of her actions
