This is like an ad for never having children.
But at the same time........the sleepless nights, the arguments with your partner(because you are both exhausted and the smallest thing can explode), the financial cost, the stress whenever something isn't right and you're pulling your hair out..........I absolutely 100000% don't want a second one. Nope. Not worth it.
So...............take that as you will :-)
My son came almost 10 years after my daughter, he's still not yet 6 and still very demanding (while my daughter was objectively less, but still I barely slept during 2 or 3 years).
I'll die young ^^;
