I absolutely 100% do feel that people without children have missed out.
I have two daughters less than two years apart in age, both in their late 20s, and they're just fucking brilliant. They have been the most amazing thing in mine and DH's life.
We've had the most wonderful life with them - from babies to toddlers to infants to juniors to teenagers - (a couple of years a bit challenging there but not too bad, and that's it!) Then college and uni- and then their 20s. One is married, one still to go. (Spring 2025.) Both settled down now. Both got their own home. Both got well paid successful careers. They're wonderful, funny, intelligent, beautiful young women and they're just perfect. I could not imagine my life without my wonderful daughters in it.
To be honest with you, I actually do really feel people are missing out if they haven't got children. I would never say this in real life of course, because it's not allowed. Though it seems to be acceptable for childfree people to have an opinion on children - and mothers. (Always negative of course.) 
I have never - at any point in nearly 30 years of being a mother - EVER envied child free people. I was childfree myself til I was in my early 30s, so I do know what it's like! I enjoyed my childfree years, and I have enjoyed the nearly 30 years of being a mother. Yeah it was fine being child free, but I would not have wanted to remain childfree.
Shockingly me and DH were able to do virtually the same things with children, as we did without, despite the bizarre and laughable attitude that your life is over when you have kids, and you can't do anything, have no freedom, can't have hobbies, can't have decent holidays etc etc. Ridiculous! You can do virtually anything and everything when you have children!
And don't anybody be coming at me for any of this - because it's my opinion -and my experiences - and it's all as valid as anyone else's. This is my only post on this thread.
