How to start solids?

💜𝑺𝒉𝒆𝒍𝒍𝒚💜 • 💙 Boy mama 💙

My son will be 6 months on Thanksgiving. I have been holding off solids until then, I am planning on giving him sweet potatoes, however my son's doctor recommended starting slow, baby cereal and oatmeal first. I would like to start now. On the box it says to start with putting it in the bottle, but my son is EBF. Could I start without putting into a bottle?? Or should I pump and put it in a bottle?? I only pump if we are going on a trip and will be in the car for a while.
