Hi, should i stick to giving my 13 month old boy formula or switch to cow's milk already? understand we should be giving our LOs full cream milk now but formula's skimmed milk right?

You can switch to cows milk however its not a must. Its totally up to you. You'll have to trial and error to see which cows milk will suit your child best. However i cant deny that it'll save you a lot of money tho 😏
