Rice cereal at 4 months?

Shay • Single mama to a baby girl 💜

My daughter is definitely showing signs that she’s ready to have cereal. She sits on her own for 15-20 seconds. Always trying to grab for my food. My dr said I can mix it with breast milk and start trying twice a week until 5/6 and gradually give more. But not to start anything else until 6 months.

Anyone else giving their babies cereal? Can it lower my milk supply?
