Hi mummies When do you give your baby supermarket whole milk?

Do you feed baby formula milk for those 2 years and up (toddlers)? My friend formula fed her child FM until primary school. Apparently there are milk for catered for older children. Please advise. Just want to know because I think I can't be feeding formula milk till my child is till primary school and they are not cheap too. #adviceplease #newmom
