I do love them and being with them (my post history should reinforce that if you doubt me); I don’t regret parenthood in the least; but their presence has definitely altered my plans for the week, especially those related to work. (I live in a rural area and have no friends here outside of my household, so socializing has not significantly changed for me.)
I loathe the rise of that “Super Parents” ideology, like if you can reorient your entire life around your children, that’s cool.
But if you can’t match it does not mean you love your kids any less.
5 really, or less depending on what hobbies
10+ is just so you can leave them home alone. You could always try to get older children in on your hobbies for bonding lol
