Any ideas on how to potty train a 3 yr old and a 2 yr old??

I'll be 50 with a 32 yr old, 29 yr old, 27 yr old, 25 yr old and 10 yr old 😯🙁
Man my 4 yr old annoys the hell out of me.. constantly asking for food.. not hungry literally just ate# NO
8 yr old question
My 8 yr old son asked me if he could be in the room while I deliver his sibling.
What's a fever for a 2 yr old
