How best to wean my son off formula?

My son has just turned one and I want to get him off the formula milk on to the whole milke but am not sure how much whole milk he is allowed and how best to wean him off the formula.

You could gradually introduce whole milk as a replacement- say, you gave him 4 bottles of formula a day, reduce it to 3, and one bottle of milk for ten days, after the ten days, make 2 of the bottles formula, the other two milk, for 10 days, and keep it going. Also, if he's not having this already, make foods similar to yours more common to him- things like mashed veges, grated cheese, mashed or stewed fruit, etc.

With my kids I replaced some formula with milk in their formula bottle. Just 2 ounces at first. So, if they would of drank an 8 ounce bottle they would get 6 of formula and 2 of whole milk. Then 5 days later I would take away 2 more ounces of formula and add 2 of milk. 5 days later take away the other 2 ounces of formula and use all milk. This way they would still have some of the flavor that they were used to but also adding something new into it. By a year old my kids only drank 3 bottles of milk. One in the morning, afternoon and evening.

Good luck
