Here is a short version of a study done in Sweden on fubber matting for dairy herd:
Concrete is the most commonly used alley flooring in confined dairy herds because of its qualities of construction and ease of cleaning. Nevertheless, the hardness, abrasiveness, and slipperiness of concrete floors have adverse effects on animal well-being and health, and yielding rubber flooring is becoming popular as a way of improving the flooring conditions on walkways. The aim of this study was to investigate preferences of dairy cows for rubber compared with concrete flooring under the conditions of a commercial dairy farm. The study was conducted in an organic dairy herd with free-stall housing. Floor preference was tested on groups of standing cows in a 120-m2 holding pen before milking, and 1 yr later on a 12- x 3-m walkway. The holding pen and the walkway were divided lengthwise into 2 identical sections. Two types of solid rubber mats (soft and extra soft) were tested against solid concrete in the holding pen. Slatted and solid rubber mats were tested against slatted concrete in the walkway. Each floor type was tested over 4 d on the left side and 4 d on the right side of the holding pen and the walkway, respectively. Concrete flooring on both sides of the sections was tested as a control before the testing of different section materials. All observations of the distribution of cows in the sections were made from video recordings captured in association with the afternoon milking. The number of cows on each section was recorded approximately every 7 min in the holding pen, and continuously on the walkway. A significantly higher proportion of cows stood on the side with the soft and extra soft rubber mats (65.1 +/- 2.7 and 69.3 +/- 2.6%, respectively, mean +/- SEM) compared with the control distribution when only the solid concrete was available (50.9 +/- 3.9%). A significantly higher proportion of nonlame cows walked exclusively on the side with the slatted (64.5 +/- 5.4%, d 4) or solid rubber mats (68.2 +/- 5.1%, d 4) compared with controls (28.9 +/- 4.3%). Lame cows within a group of walking cows did not show a higher preference for soft flooring as distinct as nonlame cows (52.7 +/- 6.9 and 59.4 +/- 6.2% for the solid and slatted rubber mats, respectively, at d 4 vs. 40.3 +/- 6.2% for control), presumably because of competition with other, higher ranked cows. It was concluded that the majority of cows preferred to walk and stand on soft rubber rather than on concrete flooring.

I hope that this information will help you,

I would second the discontinuance of the rice cereal and also tell you to stop with the jarred food as well and start giving him fresh.

He is only 9 months.. so you have a bit of time before thinking about what to do instead of formula. Is relactation an option? It would be rather hard at 9 months, but with some dedication, you may be able to produce enough milk to supplement his diet by a year.

That would be VERY beneficial as far as fat, calcium and lots of other nutrients go.

Other than that… the main nutrients we get from milk are Vit A, Vit D, Calcium and fat.
Vitamins A&D are easy. Many veggies are great sources of A (carrots being a biggie!) and Vit D is readily produced with a little exposure to the sun (about 15 min/day).

Calcium is a bit trickier… Leafy greens are good… For me, personally, I make homemade bone broth. I freeze it and then use it in cooking. Great source of calcium and lots of other stuff.

For fat (because I lost WAY too much weight after going off dairy) I take a cod liver oil supplement (also contains A&D) and eat lots of avocado, nuts, and eggs. Of these, avocado is the only one your son can have now… but since he is still getting formula, you don't need to worry about fat so much.

I would also second the caution about soy. I limit my intake and i severely limit my sons intake. Its just not worth the chance.

Oh, yes and protein… It's so common i didn't think to mention it. We eat lots of legumes… red meat, definatly… fish is great… really anything.

Chick Peas: Chickpeas, or garbanzo beans, are delicious—mash 'em up and fry them for falafel, throw them into a salad, or eat them straight out of the tin. Eating a cup of chickpeas gets you 30% of your daily protein needs.

Tofu: I never could get used to tofu; it was one of my great failures as a vegan. But 4 ounces of tofu nabs you around 20% of your protein intake—and there are a slew of potentially delicious dishes you can make with tofu. Seitan and tempeh are high protein foods worth keeping around, too.

Nuts: Eat plenty of nuts. Just about any kind will do—avoid salted nuts, at least at first, because you might find yourself eating more than you did in your non-vegan days. Walnuts, almonds, and cashews are some personal favorites.

Peanut Butter: Logic may dictate that this should be included in the 'Nuts' category, but I say there's a difference. Peanut butter comes in handy in completely different ways—on toast in the morning, in a sandwich for lunch, even as part of a chunky topping to a dessert. Now, peanut butter is the least purely healthy food on the list, so use it sparingly, and buy organic to avoid the processed stuff.

You don't need special supplements if you don't eat much red meat. Normal fortified soy milk & cereals are fine. In Asian cultures most people don't eat any dairy at all, and they don't suffer from the rates of osteoporosis that we do; too much protein blocks calcium absorption. They think we smell sour because of our dairy consumption, so it's nice to know that I don't smell sour either.

I don't have an exact measure as to size or quantity but there is cholesterol in cheese but I don't know how much.

There is 5 mg cholesterol in 370 ml of 3% milk.

Ingredients:
1 1/3 cups unbleached cane sugar
1/2 cup Spectrum Naturals Spread or other non-hydrogenated vegan margarine
3 cups unbleached flour
1 T. baking powder
3/4 t. salt
2 cups soy milk, rice milk, or other non-dairy milk of choice
1 T. vanilla
1 t. almond extract

Lightly oil a 9×13-inch pan and set aside. Using an electric mixer or in a large bowl with a hand held mixer, place the sugar and Spectrum Spread, and cream together until light and fluffy. In another bowl, sift together the flour, baking powder and salt. Add dry ingredients into the creamed mixture, alternating with the soy milk, and continuing to beat the mixture well between each addition. Add the vanilla and almond extract and beat the mixture an additional 2 minutes at medium speed. Pour the batter into the prepared pan. Bake at 350 degrees for 30 minutes or until an inserted toothpick comes out clean. Serve plain or frost with Vanilla "Buttercream" Frosting or any of its variations, or Fluffy Lemon Frosting, or other frosting of choice.

*Note: For a marble variation, reserve 3/4 cups of the batter and add an additional 1/3 cups unbleached sugar, 1/4 cups Spectrum Spread, and 1/4 cups cocoa. Pour the vanilla batter into the prepared pan. Drop the chocolate batter by spoonfuls on top of the vanilla batter, and use a knife to make a swirl pattern.

Yield: One 9×13-inch cake
