See this pisses me off because people act like life is easy and linear and you can just 'order' a baby sensibly nice and early. It doesn't always work like that.
I was in abusive relationships in my 20s (financial and emotional). It would have been a bad idea to bring a child into them A. because the men weren't suitable fathers to raise kids with and B. Because I wasn't in the right state emotionally, physically and mentally to have children.
Met my now lovely husband age 30. Didn't want to rush children as he had a child from previous relationship and stability was key. In addition, we started trying early thirties but it took us 4 years to get pregnant and I had began to lose hope. We were lucky and I thank God every day for this but imagine if we hadn't been? People who didn't know us would have looked and gone 'Sorry. No sympathy, took too long. Put it off.'
Let's face it - for most people you need to find the right person which can take time, you need to make sure that you are emotionally mature enough to raise well adjusted kids and then even when you are ready, there are no guarantees it will happen quickly.
People often assume having children later in life, or not at all is just due to 'selfish' putting it off. Just goes to show you shouldn't judge someone's journey because you have no idea. Just be careful when you're making remarks like this that you really do know the situation......I guess making a lazy quick judgment is just easier than actually having to delve deep, have some empathy and walk in another person's shoes..
