I don't think it's fair to say people on this thread are being discriminatory, I think they're just giving their opinions to the OP, which was asking what older children thought of their parents having lots of kids :)
Your large families I'm sure are great if that works for you, I wouldn't take other peoples' negative experiences as a personal slight on your own circumstances, because it is true that not everyone feels positively about being from a large family.
I am the youngest of 4 and try as I might now I have my own DD, I just don't like to see my siblings very much. In childhood, I bonded well with my oldest sister who was 7 years older than me but as adults (from her early teen years really) we have taken very, very different life paths and I have no respect for her. I hated my brothers growing up. There was no space or privacy or peace in the house. And we had a SAHP and a good income and it still didn't make up for the fact I didn't enjoy having siblings much. When I was very little having a SAHP was wonderful but at that point I genuinely don't remember my siblings being around, it was like being an only child (in my fond memories)
As a result of this I want DD to either be an only child or have a large-ish 5 - 6 year age gap between the next one, and I would never have more than 2. I also want to have my own life and time, and to have the time and money to have the experiences I want us to have. I don't want to put my body through 4 or 5 pregnancies either , or never get out of the early years while I am young.
But that's my opinion based on my own childhood, it doesn't mean I look down on people who choose to have larger families. The only reason I would do that is if you clearly can't care for them financially or emotionally. I do think that having kids isn't just about how many you want as it's such a big commitment and it is important to consider the impact it would have on them and not just your own wishes.
