What steps would you take if you were all that your baby had, but you had this feeling that you won't get to see them grow up?

My baby is only a few months old, but I have had this feeling since I was pregnant that I won't get to see her grow up. Since I am all that she has, as her biological father wants nothing to do with her, and I personally don't want her around my toxic, and selfish heartless sisters. What steps would take to try and make sure that she goes to a loving home, if anything were to happen to you?

Like do you create a will stating that if anything were to happen to you, you want your baby to not be around certain people, and you want them to go to a good home.
