There's no doubt that you have a lot on your hands with 7 kids. I don't personally see the issue with big families, I admire those who have one.
But, it's the 4 different fathers that's hard not to...wonder about and, yes, judge. The amount of different fathers show that you have a consistent pattern of making bad choices when it comes to men - and within a relatively short period of time according to the information in your posts. Which, yes, tells most people that you jump from man to man and aren't careful about who you have kids with. And it indicates that you introduce your kids to too many different men, too quickly. I'm sorry, but that's hard not to judge...I just feel bad for your children, really. It's always messy with half and step sibling relationships in more ways than one.
I don't understand your laughing emojis when you respond to posts, and joke about "not wanting the man, just the baby". It actually seems to be an accurate reflection of your true attitude towards parenthood: you don't see the severity of having so many different fathers to your children. In the end, yeah, you got your babies, but your 7 children are robbed off a normal nuclear family setup. Congratulations. As long as you got what you wanted.
I'm sorry if I sound harsh, I'm just so, so sad for all the children that can't have a life with their biological parents and siblings just because the parents keep making bad selfish choices. Enough is enough with all of these broken and blended "families". They don't work.
