Breastfeeding a toddler after c section advice please!

Cookie

My toddler will be almost two and a half when I have my c section.

He feeds a few times a day and a few times during the night (we co sleep).

How quickly can I lay flat on my side after a c section to feed him?

Can he sit on my lap to feed the day after if I don’t lift him?

I’m starting to feel very anxious about it.

I have two months to prepare.

Thank you!
