I honestly think that no matter what women do there will always be someone with something to say about it:
Has no children - "you'll never know true love until you're a parent", "it's selfish to live for yourself", "who will care for you when you're old", "you'll have no family to visit".
Has children - "why are you complaining? You made this choice!", "You chose to get pregnant, you stand up on the bus like everyone else", "I don't care if your circumstances have changed, if you can't feed 'em don't breed 'em!"
Has 1 child - "They'll be lonely!" "You can't expect them to grow up with no siblings!" "What about when you die, who will they have?"
Has 6 children - "I don't mind as long as they're not using taxpayer money to feed them", "probably wanting more benefits", "insert misogynistic and grotesque comments about the woman's vagina after having multiple children"
A stay at home mum - "You should do all the housework/childcare/admin as your partner works", "lazy", "you should be lucky your husband pays for you to stay at home!"
Working mum - "your child needs you at home!", "why have a baby if you're going to get someone else to raise them?", "is a job more important than time with your child?"
The point I'm making is that in someone's mind, whatever you do will be wrong somehow. But these people are all strangers, and if they're people you know in real life who are saying these things, set them straight. DO WHAT YOU WANT! It's your life, you only have one, you have to make the decision you feel is best for you without pressure or coercion and anyone with the ignorance to be nasty to someone regarding their valid decision, just because it isn't what they chose for themselves, needs to simmer down and realise they're not as important as they think they are. We are all independent people with different lives and circumstances, children fit better into some lives than others and it's nothing but the individual's decision which is important when the question of having or not having children is concerned.
As a woman in my early 20s, I think I'd like children one day. Most of what's put me off parenting is what I've heard from other parents who talk about how tired they are, how exhausted they feel, the sleepless nights, the school runs, the hit to your career etc. I still want to be a parent but that's why I'm solidifying my foundations in life first before I decide if I do want to try and have a baby.
I don't want to TTC for a few more years yet as I want to qualify in my chosen career and buy a house first, but also I have a medical condition which means I may end up being unable to conceive and have therefore developed the attitude of "it'll be great if I do have kids, but it'll also be great if I don't have kids" and I genuinely believe that. Although, of course, as someone who would like a child one day I would feel sad if I did find I was infertile, it's not my "be all and end all" and I have two vague plans for my life, one for if I am able to have a baby and a plan for if I'm not. Both plans seem great to me, both have their pros and cons and I'll await to see which one will come into fruition when we cross that bridge.
I've already faced nasty comments from people (mainly my nan and her friends) who were shocked and genuinely disgusted when I said I wasn't sure if I would have children when I was older. I didn't want to disclose my personal medical details about the fact I may be infertile, nor should I have to, but I was met with lots of confusion about what I would do with my life, comments about how a career isn't worth a fraction of what a child is etc. Just general, disheartening comments phrased to make me feel bad about a decision I have no say in.
