Why do people say i'll change my mind?

A lot of people can't see beyond their own thoughts and just can't grasp differing opinions.

I would say adopt a child before giving birth to one. There's so many kids out there that need love and support. Or being in foster care is good too. Also there's a bunch of animals that need a home too. Adopting an animal is kind of like taking care of a child. But that's of course IF you change your mind. If YOU don't want to have kids then don't. Don't let people guilt you into it. Everyone's entitled to their own choices and opinions. And it will save you money, & time. And this world is already over populated.

Because a lot of people felt that way before having kids either on purpose or by accident and ended up eating their own words.

Parenting is hard, but it has its rewards. If people went around saying "parenting is easy omg" then they would probably be looked upon as bad parents. Parenting is hard, but it makes up for it after all of the years of changing diapers and dealing with temper tantrums, you get to watch the product of your hard work walk across the graduation stage, get a job, become a productive member of society, become a great teacher or soccer player or whatever they choose to do. In essence, you get to see all of your hard work legitimately contribute to society.

There's something different about raising a nurturing another human being. I'm not a parent myself but I'd like to be. If you don't feel that way then I hope you have other passions in life but for some people, raising kids is a passion in and of itself and it's no less worthy than any other passion on this Earth.

I used to say I didn't want kids, but I changed my mind instantly when I got knocked up. I don't understand why people who are younger than you, especially if they don't have kids, would say that. Some people just don't want kids and I can totally understand why. I think Armus is right though because I occasionally have to fight motherly urges to convince people that kids can happen to be the best thing ever.

Humans are human, and therefore our opinions are subject to change, usually when presented with new information about the subject.

Because it's meant to be the "right" thing to do and your life is meant to be empty without it.

Reality is, it's not for everyone and if you can accept that about yourself rather than having a child because you're "meant" to, that makes you a good and very non selfish person. It's selfish to have a child to fit in with society's expectations. Not everyone does this, obviously, but too many do. You may not change your mind and that's fine, and if you do end up changing your mind, that's totally valid, too.

People mean well, but it just ends up really patronising.

As you age, the biological imperatives which want you to procreate become stronger. You say you will never have children. That may be true, but biology has a way of making you rationalize things you may never have considered. Some people can resist and some can't. That is why they say it. Their will was weak and they believe you are either just as weak, if not weaker.

People say you'll change your mind because it scares them that you don't want kids. People think every woman has to want to be a mom or else she's selfish or inhuman. It's their problem, not yours. They have to learn to open their minds and actually think.

Not everyone should have kids or be married, either. I know people who feel everyone should have at least one but...why? Theres enough. idiots who have babies that they don't care for because they are too stupid or careless to use birth control. If anything your being responsible.
I never wanted kids either, I had one because my husband wanted a baby but it was very difficult for me. I had depression and kind of shock from the lifestyle change and I didn't really enjoy being a mother until I got mentally stable. I love my son but I would never have another...if youre sure you don't want to, don't let someone tell you otherwise.
A good all round answer is "I think the world has enough people!"

Because they think it's a great thing and it's odd to parents how others don't want the same out of life. Only you know what you want in life. Don't let anyone tell you otherwise.
