EBF transition to cereal and food?

My babe was born on July 13th and has been EBF. The doc said we can start rice cereal anywhere between 4-6 months but haven’t started yet.

I’m curious how you moms start implementing cereal. Do you pump during the cereal feedings? How often do you feed with cereal?

I feel like we’ve finally gotten a schedule down pat and now it has to change 😟
