Moms with 4 kids please LMK

So.. we have 3 kids already but we are considering having a 4th.

I just wanted to ask for the mamas that have 4 kids do you regret it or enjoy it?

(Nobody regrets any of their kids, I just mean do you find it way harder? Would you go back to just having 3 if you could??) just wondering. Please let me know mamas!
