I feel that my relationship changed with my parents cause I don't want to have children?

Is this normal for this to happen? Like I understand they still love me but I feel they are unhappy with my decision, all my siblings have kids and they don't like the fact that I don't want kids, my sister even said she wanted to make a distance after I get married to that somebody one day, not sure what she meant by that.
