Just that really. I see so many stressed families around these days and understand there will be other factors as to why. Everyone I know who has chosen to have one DC (or indeed child free) seems markedly less stressed, with more free time. I know they grow up and imagine it would be nice to have multiple adult kids coming home for Christmas and to share lives with but there’s a long 20 years to get to that point, where most families these days need 2 working adults besides will be having kids older and retiring later.
