Quick Quaker (oats) Question

[suzywong]

I have bought some Quaker oats which I want to use in place of the expensive ready-mixed sunshine/museli dry baby cereals. I intend to mix them with fruit puree and boiling water for baby DS2, just as I did with the sachets.
However, I noticed on the packet that I have to simmer the Quaker oats for 5 minutes! I don't want to faff around with pans for such a small portion and I have my breakfast an hour later (only chance I get) so we can't share.
Could I just mill the Quaker oats more finely in my food processor or make up batches of oat porridge and mix it with the fruit puree and freeze in in icecubes?
As you may know I am somewhat stubborn and am loathe to go back to the ready mixed sachets without asking the wisdom of MNers if there is another way.

TIA

you could make ahead and freeze - but couldn' you just microwave it instead? or would it be too small a portion?

Don't have a microwave. Should have mentioned that.

Suzy, I'd have thought an oat/ fruit puree mix would freeze fine. But if your oats are the size of my oats (Jordans) I guess milling them first would wise. Mine are almost the size of a postage stamp! Yummy though. Dd doesn't get a look in at porridge time in our house.

I've frozen porridge before - you do seem to need to add extra liquid when you thaw and reheat it as it tends to go quite thick.

thanks everyone, I knew you would know, you know
