What Shiv said!
Toddler milk is really not necessary despite what they say on the TV
and costs waaaay more than cow's milk. Formula companies can't advertise their first milks which is one reason they have developed goodnight milks, toddler milks etc for babies over 6 months. Formula is also quite filling and as milk isn't a food once they hit 1 they don't need to be filled up on it. From 1 year they only need around 14 - 16oz of dairy and that can include the milk in foods.
HTH!
