Cool to read - and nice to see how hard you are trying.
Now imagine I have three of those and a fourth on it way .... you need completely different concepts to stay on top.
And what seems true is a saying they habe here (I hope it translates well) - small kids small worries - big kids big worries ...
I can't even imagine what it must be like to have to keep an eye out for 3 of them! My goodness. It's impossible to do alone, I would think. I get your translation perfectly. But the big worries are for later :)
