Congratulations!
But HOW DO YOU HANDLE IT? I have one and feel overwhelmed half the time. I think 10 would kill me.
First - two is easier than one, if they're close enough together, because they keep each other entertained and we have more free time rather than spending most of our time figuring out how to keep them happy.
To answer that seriously would take a lot of thinking and could probably fill a book, which I'm not about to do. There are a lot of mitigating factors, and the children grow and have to learn to manage themselves more than I suppose they would in a smaller family where they'd get more individual attention. Our one-on-one time is brief periods in the car when we're driving one child or another to someplace or another, and a little semi-individual time with each one at bed time. Otherwise it's almost always group interaction all the time. As you run out of hands, they learn to walk and open doors so you don't have to hold the older one's hands. About the time we're losing our minds because we're never free of them the oldest becomes mature enough to babysit for brief periods of time, then another, then another. About the time we're running around, just driving an hour or more a night getting everyone to various activities, the oldest two get their driver's licenses. We work hard to avoid placing too much responsibility and pressure on the oldest few (they are not parents, plus we pay them for some types of babysitting to differentiate between duty and job), but we rely on all of them to contribute in whatever ways they are capable. While my wife still manages to cook a big meal for everyone each night, with at least one helper (who slows her down, but we want the kids to learn to cook, or at least feel comfortable following recipes) who also sets the table, then everyone pitches in to clean up afterwards, starts the dishwasher, and tidy the place up.
Despite the amount of work, they all still manage to get in an hour or more of games, videos, or other entertainment daily, keep up with their homework, and chores. We have a family meal once a day where everyone sits and eats (yes, it's chaos - but that's just normal around here, we've got 3 kids under 5 years old).
And we love them, as an active choice in our interactions. We can't mold them or force them into place, we love them as they are, how they are, and recommend paths and courses of action (scripts, to some) we've found valuable or useful. But at the end of the day they have to have their autonomy, and we have to make sure they know that whatever their choice we will always love them. But we're also happy to let them deal with the consequences of their choices. We might remind the younger child that they should ask for help pouring the milk, and when they spill we may help them clean it up, but by way of instruction and demonstration as needed - not doing it for them.
We don't use corporeal punishment, and I work hard to avoid guilt - they take themselves on enough guilt trips, I certainly don't need to add to their burdens. The desire they have to please us is extraordinarily strong and we have to actively work to make sure we're not abusing that seemingly innate desire. Whatever path they choose through life we want to have a strong relationship with them and with those they choose to be with.
The biggest thing, though, is I've chosen this life, and they are my highest priority. Which means that at this stage of my life I don't have anything else (I do, but I"m careful not to let outside interests get in the way of family). I really don't do much for myself - if I need to refresh and recharge I choose activities that are suitable for or involve the kids along with me. I'd like to play with RC cars, if I do it'll be by getting one for the kids and getting them into them, for instance, or watching a new anime together. The reason I've chosen this path is because I believe that what I'm building now will last forever. It'll certainly change over time, but
our family will be family for all eternity. So while I'm giving up much of myself right now, video games may come and go, movies will be replaced with newer movies, and I could consume - or participate - in other human experiences, only a few things can be built here that will last forever, and I believe my relationships with my family and friends are one of the things that transcends death.
So that's what I focus on.
And like any good addiction, you develop coping strategies and tolerance. At this point adding another baby to the mix really doesn't seem like a burden at all, just an addition of joy, an opportunity to get to know someone new and help them take their first steps in this life, then watch them fly and see what they do.
And having explored the very tip of the iceberg, I'm going to leave it at that. But if you have more specific questions I'm happy to delve into it, I don't think about it much, I just do it.
