Qs about T W I N S S S S

Hi! Based off of my LMP we went for our first ultrasound last week. Turns out what I thought was my last menstrual cycle was implantation bleeding. I am measuring 11 weeks with TWINS! We are planning to move to a bigger home but have a few questions, I am 5 weeks further along than I thought I was so trying to plan accordingly.

What week do doctors put patients on bed rest?

What are must have twin products?

Can I hear from moms pregnant with twins post c-section?

Our firstborn is 1y5m when would you suggest potty training? Or moving to a toddler bed?
