They say to give full fat up until at least 2.
We're not scared of fat in this house, but I prefer skim or hilo. Given that any milk which has less fat has more protein and calcium - there's a trade off happening which ever way you go.
I did change my kids to drink hilo - not because I was worried about their weight, but because I wanted to only keep one type of milk in my house . I did it sometime after they were both 2. I figure the extra calcium is a good thing anyway.
Canola isn't a vegetable oil. It's a grain
I use canola spread instead of butter or margarine.
