Full cream milk

Hi mummies and daddies! My baby is turning 1 soon and i've read that they have to be transitioned to full cream milk instead of formula ones already. Question is.. So i'll be feeding him full cream milk for his diet and there's no need for formula anymore? His drinking routine is formula milk every 3 hours. So these feedings of milk have to be replaced by full cream milk + solid food? #pleasehelp #firsttimemom #firstbaby Thank you!
