First, never go by what is stated on the front of a box or package...only go by what is listed on the "legal" nutrition label, and learn to read it.
So, for example, in "100% whole wheat* bread there will be some fat because the healthy germ of the wheat that's usually removed from "white" breads when they're milled is still present and it does have a little bit of fat (the fiber-rich "bran" has also been removed).
For other bread terms, "whole grain" means the bread may contain other whole *grains* besides wheat (like oatmeal, or buckwheat, etc).
The important things to look for in bread are that it be 100% whole grain/wheat, not just "made with whole wheat/grain" since that could mean that the whole grains are only a small portion of the total flour that's used. Tricky, right?...it's that way intentionally though unfortunately because the advertisers want to you think their products are healthy or whole grain or whatever by just using those buzzwords (on the front of the packaging especially).
I also try to find a brand of whole wheat bread that doesn't have high fructose corn syrup (HFCS), but that isn't easy to do. With all the negatives coming out about those, some breads (and many-many other foods) may be moving away from them but not quickly. Btw, "high fructose" corn syrup isn't the same thing as corn syrup even though it started out as corn syrup.
Totally whole wheat/grain breads can taste kind of dry and "stiff" though, so I always try to buy one that kind of squishes nicely when I pick it up (not Orowheat, for example...I usually get the Organics' brand 100% whole grain wheat bread, but I shop at Safeway and you may not).
The term "natural" hardly means anything these days, and can actually mean the food has a lot of things you wouldn't want if you're trying to eat healthy.
The term organic is a little better, but even that isn't always 100% what you'd think it is. Still worth going for if it's not out of your budget.
Sprinkling wheat germ (or wheat bran, or ground flax seed, etc) on his food, or mixing it in, is nice but not really necessary if he's eating nutritiously otherwise.
If you're wanting to go "healthy," you can read up about all that at various sites, etc (see below), and you will definitely want to learn to read nutrition labels since that's about the only way you can really tell what's in something.
The main things you'll want to look for will be the total amounts of:
...fat (learn about the good and bad "types" of fat though)
...sugar
...sodium (including, but not limited to "salt" which is sodium chloride)
Fiber is important too, but those 3 are first on the list. Both insoluble fiber and soluble fiber are good, and often found in healthy foods.
The legal "ingredient list" is also important because that lists (from most to least) the actual ingredients, not just whether they have fat or sodium, etc.
There you'll also see the list of preservatives, additives, colorants, etc.... in general, the fewer the better.
The "serving size" is another potential trip up from the advertisers since that's what the numbers will be for -- *one* serving size. You've got to check just what they're calling a serving size since it can be much smaller than anyone would consider a regular "portion" (so they can artificially deflate the numbers you'd see for a real portion size).
Most "processed" foods (those that are different than how they come off the plant or from the animal) are crammed these days with way too much fat, sugar, and sodium, even when you wouldn't expect those flavors to be in a food. Sometimes they're there just to make the shelf-life a lot longer, or to make them cheaper to manufacture too.
So if possible, it's best to eat "fresh" vegetables and fruits (or frozen if you don't mind the texture) as much as possible, for example, and to avoid heavily-processed packaged items. You'll be avoiding all the additives, extra chemicals, etc., etc., too.
And there's also *cooking* healthy. Many recipes can have good things in them, but may also cram in a lot of fat and/or sodium in particular along for the ride.

P.S. You do want to avoid giving your son honey or yogurt till he's at least one (maybe two, can't remember) just because those have bacteria that *may* not be well tolerated by those with immature or low-functioning immune systems.
Congratulations on the new healthy eating habits for your son and for you!!
