Something that strikes me is that most people stop having children at 1 or 2 because it's so hard. Everything or nearly everything has to be purchased for the first time or again because both dc need the same things at young ages, the chaos is real and the idea of having more of that is terrifying.
It truly is!!!
What I have very rarely had the opportunity to share with others irl, is that when there are many children, the relationships and their dynamics change so much that it is never just like having two, but doubled or tripled or whatever. It is just totally different.
When we go to a popular indoor playground here, our four boys with their variety of ages and maturity levels, can and do easily accommodate children there with ease. They are supremely generous and don't hesitate, because generosity and accommodating the needs of others is inherent to our daily activities and worldview. They can make up a game that truly incorporates the desires and ideas of ten children of various ages, all of their weird ideas and characters, all of their physical qualities- limitations and excellence inclusively- and it is shocking to most parents watching from the sidelines. They cannot understand how a vigorous game of hide and tag and role-playing can incorporate children who are crawling to children who can and do jump right off the tops of the 8 ft ladders/poles and slides.
This, and amongst myriad other examples of how this life is just different and not just a lot more of the same, children with many siblings do not have to engage in conflict when one of their siblings is not interested in something or disagrees. That not everyone will agree is expected when there is such a variety of perspectives to consider daily and minute-by-minute. They have other people to go to for what interests them respectively. If ds1 wants to sit quietly and read a lap-sized book while sharing it, and ds2 doesn't want to, ds1 can ask ds3 and/or ds4, and usually, even with only four, the odds are pretty good that someone will be game for just about anything at anytime.
Mum and Dad are also not the only people who can facilitate the childrens' needs, and this is not to say that it is a luxury of neglect afforded by having many children, just that there are a lot of needs to meet with any one person, and being a child with one brother and having a vastly different experience of childhood than did he, I can say that what my dc have- someone else, maybe someone who will understand certain parts of them better, be a more cohesive partner for certain things at certain times- would have gone a long way to curbing my immense loneliness as a child, and that of many adults who I know irl, who had one or no siblings (not to say that this is a universal experience).
It is hard with many children closely spaced though, but my perspective on that really took a hit a few months ago. I worked in a daycare for my friend for one day (ds4 came with, but would not sleep at night, so I had to discontinue what was to be temporary anyway). I looked after all the needs of 10 children including my youngest who was not yet 2 yrs (but who demanded nearly none of my attention, although I scooped him up all day to fill in what he seemed to not ask for but I knew he was accommodating to his own detriment- a personality thing for him). That was one of the easist days ever. It was like taking a vacation, but it wasn't good.
The children were 'easy' because they were placed in a context where they did nothing for themselves or one another because they had no bonds with the other children and the daycare staff do everything for them. So in other words, they could all just wait with their hands out for me to meet their every need. In my home, my dc are engaged with one another, with me, with dh and with the world/our environment at all times. There is such a lively buzz to that, and even though it is hugely challenging to this extremely introverted mama, I wouldn't ever trade this for anything. The immense benefits to my dc for having one another are too obvious to ignore for even the most staunch zero-populationist (mil, for instance).
I found two children to be a 'hump' to get over. Three children was waaaay easier than two and four has been just different. We're expecting our fifth, although my measurements are pretty huge, so maybe fifth and sixth- we'll see- and I have no doubt that whomever this little person is, s/he will have a natural place too, amidst the buzz and humm of our life.
I am very obviously pg (16 weeks, but huge- 23 cm), but this time around, nobody who doesn't know me has said anything other than 'Congratulations!' We have found this area to be quite open to families of all sizes and make-up, which has been a wonderful change for us. I had people making rude remarks when I was pg with ds2 where we used to live.
