DS is one now and we've been working on trying to get him to transition to whole cow's milk for maybe a month now. We've done the whole mix it half and half with formula thing, and he's NOT having it. He will occasionally allow us to mix it 1/3 WCM and 2/3 formula but even then will sometimes pick up on it.

He's obsessed with drinking out of his straw cup or adult glass cups so we've tried both and he still refuses. The little stinker will watch me pour the milk out of his straw cup and fill it with fresh water and will happily run over to take his water cup from me - he's just so obstinate about WCM!

Anyway - we need to get him off of formula both for budget and simplicity's sake! Does anyone have tips? Was anyone else's child a hard sell for WCM?
