Giving baby solids

Lauren • Had my sweet girl 02/22/20 - 5 weeks early due to rare genetic disorder💗 Had my handsome man 09/30/22 - 3 weeks early due to low birth weight💙

My daughter is 4 months old. They gave us a sheet at her last drs appt showing eating recommendations. It says 4-6 months to starts baby cereals and some fruit and veggie baby foods. How old was your baby when you started letting them try baby cereal and food? How do I know my baby is ready?
