I'm in AB and feed the kids quite well. Lots of fresh fruits and veggies, mix of organic and non-organic depending on the type (I use the ewg dirty dozen and clean 15 as a reference of which to buy). I started the year planning to claim $7/day/child, but after doing the calculations I've found it's over $8, so when I do taxes I'll change it then.

I think it's reasonable based on what I buy, but I'd still have all my receipts handy in case you do get audited. My accountant seemed to have no problems when I mentioned doing $8.
