Hi Cre8tivgrl!
Congrats on the impending new arrival!
As far as fruits go, the lower the glycemic index (GI) the better. You might want to do some research on the net or get a book that lists the GI of different fruits. Bananas and dried fruits are usually very high. Fruits like berries, melons, peaches, oranges (maybe half at a time), apples (again, maybe half at a time) would be good bets. Fresh is always better than canned, but frozen would work in a pinch too as long as there are no added sugars.
As far as grains, go for the least processed possible, wild rice or brown rice would be good choices, but keep the amounts small.
Instead of adding milk, how about some plain yogurt? Less carbs, but still lots of calcium. You can even add some Splenda and berries to it yourself.
You can also keep your carbs up a bit by using some of the veggies that are a bit higher in carbs like sweet potato and winter squashes.
I think if you stay away from the highly processed things like bread, flour, sugar and pasta you'll probably be fine.
Happy baby!
