Infants would have been breastfed until they typically weaned themselves, which would probably have been around the age of 4 (possibly older) so dairy is probably good to go as long as it's raw, grass fed, or failing that at least organic and absolutely definitely FULL FAT :D My little 3 years old girl loves full fat milk, and heavy cream, and butter actually, she's a proper little Paleo lady :D

I wonder what the RDA is based on? I would not be surprised if it is trying to limit saturated fat, in which case it is to be wholly ignored.

From what I understand, goat's milk is more digestible, and the composition is more like human milk, but I haven't verified this.

ETA: A quick search seems to indicate that goats milk has slightly less lactose, more short-chain fatty acids, and more highly digestible fats, and a different kind of casein that fewer people are allergic to.

Also, aren't goats usually pastured? I'm not sure about that.

One thing I would keep in mind is that goat's milk is naturally lower in fat than cow's milk. I'm sure you'd have no trouble making up his fats elsewhere if you decide to go that route, though.

Kudos to you for raising a paleo child! :)

According to the what the literature says goats milk has been found to be less problematic in terms of any allergic response in the human body. The goat proteins are assimilated better by our gut compared to bovine proteins since goats are not ruminant animals like cows who have 4 stomachs. Children's guts are naturally leaky in early phases of life so that they can absorb and digest proteins and immune globulins from their mother's milk, and eventually the gap junctions of the gut fuse within the first year or 2 of life. Cow's milk can be problematic since the larger proteins can pass through a leaky gut and the body can produce an autoimmune response. This can lead to atopic diseases (asthma, allergies, eczema etc) and an overall lowered immunity and inflammation. Goat proteins are less problematic and are less likely to cause immune reactions. To reduce your little guy's risk of leaky gut issues it is important to minimize grain and legumes. Other gut-inflammatory items can be medications including antibiotics, processed foods, and homogenized dairy. Overall if you choose to give your child dairy, goat is a good go-to, then raw cow milk, but a good idea to minimize homogenized cow's milk for gut and immune health. One more thing, the USDA tells the public that milk is necessary for your child but this is totally false. There are only monetary motivations behind this recommendation and none in terms of optimal health and function. Children (or adults) are not really designed to ingest daily amounts of cow milk. Cow milk is perfectly designed for baby cows, but not so much for a developing human. Hope this helps!

Goat and sheep milk is less allergenic than cow milk is. They are also naturally "homogenized." That's the only difference I know of but within cow milk there are huge differences too depending on whether it's been pasteurized and whether it's A1 (most store milk, Holstein) or A2 (Jersey, Guernsey).

My suggestion is do all you can to research and find out how to raise goats. Either get one or two or find a very reliable goat person, they are all over the USA who will give you fresh raw goat milk for free. No legal problem. You can simply offer to give something, a gift, to them for their generosity. Milking seasons come and go, so its always nice to get several sources. If you are out east this should be no problem!
