How do you make oatmeal for your baby?

Just curious! Today was night 2 of trying oatmeal for supper with our little guy. He's been doing well with veggie purees and finger food. The instructions we got from our doctor say to make just normal adult oatmeal (full fat cow's milk, normal oatmeal, adult thickness -- can use water or breastmilk or whatever to thin it out). It also says to add 2 TB of fruit juice or fruit puree so we've been using bananas (it's what I had on hand -- I know they're both constipating but we've never had an issue).

So how do you make yours and how does your LO like it?
