Breastfeeding and rusks/porridge

My little one is 5months and she’s been breastfed since birth, I want to continue feeding her myself but have had numerous people asking when I plan to give her solids. I am considering starting with porridge but am worried this will affect her feeding from me as I don’t want her to become fussy. She’s not fussy and is quite content after her feeds so she’s not looking for anything more, a don’t know if anyone else maybe felt pressured into giving their baby solids to save other people commenting.
