Am I wrong for starting to dislike SO's family?

So my boyfriend's mom wanted us (my two month old daughter and I) to go over to eat at her house a few weeks ago but I kindly declined to go because my boyfriend's brothers including his step dad smoke weed in the house and will definitely not have my daughter around that environment. Not only did she get upset but also his siblings at the fact that I said that I wouldn't go until they stopped smoking in the house. I know she's my daughters grandma but I feel like she doesn't respect my daughter or me at all and only cares about seeing her and not her well being. Because if she did she would understand why I will not take my daughter there. If I remember health class correctly when you smoke in a home the smell also attaches to the furniture, curtains, etc. so I chose to not take my daughter there at all since her immune system is severely delicate. I invite them to my house but they're "always busy" and will not take my daughter out unless it's a medical emergency because she hasn't received her shots yet. P.S: YES I KNOW CIGARETTES ARE FAR WORSE THAN THE SMELL OF WEED BUT AS A MOM I HAVE THE 100% RIGHT TO CHOOSE WHAT ENVIRONMENT I DO AND DONT WANT MY DAUGHTER IN PLEASE RESPECT THAT. via /r/Parenting http://ift.tt/2FfR4Q9
