Women have been judged for their reproductive and other choices since time immemorial. You're judged for being too young, or too old, or in a relationship or not in a relationship, for working or not, for claiming benefits or not, for being part of the pta or not, for taking them to clubs and activities or not, for packed lunches or school dinners, breast or bottle, too fat or too thin etc etc. To an extent you have to harden your heart and crack on.
However, I do have thoughts and opinions about large families I see at school, especially with a single parent who has their own personal issues due to negative relationship experiences, becoming a parent very young or without the financial resources to manage well. It looks such hard and unhappy work from the outside, the children are often the ones without the right stuff or late and the parent is often seeking help and support - and schools try to provide what they can but are limited in what they can do. I personally couldn't manage more kids and do it well so absolutely don't blame someone for not coping well but it is then very odd to see these families get steadily bigger. A mum at our school would always complain on the class WhatsApp about modest dress up day costs or once a year trip costs and say "when you've got 6 it's 6 times as much" but then had another baby! These children and their parent rarely look to be having ana easy or enjoyable time, and don't get to do any extra activities, trips, outings or clubs. This particular mum had a few children with specific learning and behavioural issues and was often called into meetings and needed to attend more appointments etc than the average.
Op, if you want a large family (and I think it can be wonderful in good circumstances) then you need to make your decisions and live your best life. But expecting people not to judge when they judge about almost everything else is naive.
I do think the lifestyle expectations and income differences in society are widening too. So many people stop at 1 or 2 children due to wanting to be able to provide housing, holidays, education, music lessons, clubs, cultural experiences such as theatre trips and museum visits, weekend breaks and holidays abroad, plus wanting to pay for driving lessons, cars, uni and house deposits. It can be hard to understand that other people are happy not to provide any of those things and see them all beyond basic food, shelter and company, to be surplus to requirements. It's 2 cultures colliding really.
