This thread has made me feel so much better. I am 28, childfree by choice and never intend to have kids and I feel very alone in this decision in my peer group.
I didn't always feel like this, but over the past couple of years I have done a total u-turn from wanting a kids to not wanting any. A lot of my friends have had babies recently and it really cemented my decision that having my own was just never going to be something I wanted. I value my career, being able to travel, make spontaneous plans and being able to spend the money I earn on enjoying myself and the things that I like. I will happily admit that I am too 'selfish' to have a child because I enjoy my life the way it is.
I am also quite an anxious person and the idea of having to worry about another human being who's needs and wellbeing are solely my responsibility is unbearable. My parents keeps telling me I will change my mind and how much they want grandchildren, which is really getting me down. I have achieved so much in my life that I am very proud of, and yet I feel like to them, nothing would be as good as if I were to have kids.
Another thing I have found, and I am quite curious if anyone else has experienced this, is that if you are childfree, it is also assumed that you can't stand children?! For me, this is not the case at all, and I absolutely love spending time with and spoiling my friends' children. I just love being able to hand them back to their parents!!
