I never added lemon juice ever and I’m not dead yet. But with small kids, I’d be uncomfortable with having forgot.
Because when my kids were small and I was preggers, stuff worried me more and pregnant women need to sleep, not worry.
So do what gives you the most peace of mind so it doesn’t naggle you in the back of your mind and mess with your head.
My self, I’d probably drop them into the pressure canner to relieve my worry with the least amount of effort.
Now that they’re teens, sometimes poisoning them seems almost legit.
By the time they hit 30, they can be a blessing to have around. One of my daughters is a blessing, anyway.
