Is formula a necessity??

Alexia

Good afternoon ladies , I just have one quick question I’ve been debating on this for a while so here it goes:

I plan to breastfeed my babies for as long as possible hopefully till a year, then give regular milk i really don’t want to use formula unless I have to have to ... so my question here is if it would be such a bad thing to not give formula at all if my milk does last me.... or is formula a necessity.

Thank you in advance for your opinions ladies !! 😊
