Our kids are, as of now, 8 (almost 9), 7, and 3.5. We've had the time to adjust to being a family of 5. Well, sort of. It is hard to adjust to anything when the kids are concerned - they change, their habits change, their likes and dislikes change. As soon as we adjust to one thing, it is time for a change.
I think I wrote this already - I am glad I was completely oblivious to how hard parenting can be and how much work is involved. Oh, I definitely feel that my life is very rich and full of joy - but also, you know, exhausting.
It is amazing how much quieter an individual child is, compared when all 3 of them are together. I love having breakfast with our 3-year old - we chat, we discuss things - and I never have to ask her to keep her voice down. Not surprising really - she doesn't have to compete with the 2 older siblings. When I take my son for a "date" - he talks non-stop, but he doesn't whine. He just has so much information to share! My older daughter - we like going to a cafe or a bakery together, to have treats and bring more treats for everyone at home. She is the one who really keeps her thoughts to herself. I never really know what's going on in her head - but when she does talk, she is incredibly thoughtful and really analyses the world around her.
The most difficult thing is the competition: "Mommy, listen to me!" "No, I was here first!" "Mommy, mommy, look here!" - all three of them all at once. This has been more of a challenge than bickering and fighting among the kids (that happens, too). I have not found a good solution, yet, so dinners with everyone sitting at the table tend to be loud (and stressful).
While I am on the subject of dinners - we are struggling to enforce the rule of "stay at the table until you've been excused." The whole "may I be excused, please?" seemed ridiculous to me, until now. Because now: kids are running off and coming back to the table, not finishing their food, then coming back to finish it an hour later. We definitely need to work on good manners...
Our life (talking about adults here) is incredibly stressful. We have demanding full-time jobs. And then, when we get home and are ready to collapse and just want to rest, we need to have the wisdom and patience (ahem, right...) to deal with sometimes whiny, often impatient, and always demanding three little people. And dinners, and baths, and bedtimes, and homework, and lunches, and innumerable other things. Did the addition of the 3rd child create more stress and more work? Absolutely. More driving, too (more childcare pickup, more dr appointments, more activities). And we haven't gotten to the point in our lives when kids have multiple sports/music/other hobbies (for now, the older two are doing a max of 2 activities a week, music and sport, and the younger one is just doing a weekly gymnastics class). We also haven't been scheduling any regular playdates for anyone (they happen, but rarely).
We try to have things as simple as possible... A simple life, a minimalist schedule, a minimum of housework we can get away with. Clean laundry sits in the basket for days before we get around to folding and putting stuff away. We outsource house cleaning. We make simple food that can be stretched for more than one meal and rarely bake.
If we only had 1 child - would there be more travel? Maybe. Would there be more trips to museums, more activities, more weekend trips to cafe? Possibly. I feel like all that can be done with 3 kids, too, once the youngest just gets a tiny bit older. The older 2 are usually very good in public - they behave at restaurants, museums, concerts, etc. The youngest definitely throws a wrench in there - somehow, the balance shifts and everything gets more wild. I do hope that it's just a phase she is going to grow out of and not a permanent personality trait :)
