Is is true by giving my baby processed food like Cerelac will make my little one a fussy eater? My baby is only 9 mth

Hi mummies, I’m a first time mom here. I’ve been hearing a lot about not to give baby processed food like cerelac because it will make one become a fussy eater? I mean is it true? And is it proven? My baby is only 9 months! I mean preparing food for my baby is already so time consuming when my baby is a clingy child😩 Tia! #1stimemom #firstbaby #pleasehelp
