"Paleo is not about re-enactment. Paleo is about making informed choices in a modern world."

Well said, and I whole-heartedly agree.

The best we've found is the Hipp Organic formula. I spent more than an hour in our local Edeka reading ingredients on numerous formula packages. It had the least amount of bad stuff in it. My wife hasn't been able to produce enough milk for our rapidly growing twin girls (7 weeks as of yesterday), so we had to bite the bullet and find some formula. We are feeding them the the Hipp Bio Combiotik 'Pre' formula right now.

I know some Paleo people are totally against it, but you need to do what is best for you and your family. We didn't want to feed our girls formula at all, but we really had no other choice. Being an American living in Germany, trying to track down all of the ingredients to make the Weston Price formula has proven to be very, very difficult, especially in the ass-backwards region we live in. However, we both strictly adhere to the dietary portion of 'Paleo' (more Archevore Kurt Harris if we must label it), so our girls are getting some good breast milk for at least 1/2 of their meals. We have actually seen little to no difference when they are fed the Hipp formula vs. the breast milk.

I'm thinking you should be able to find this in Belgium quite easily. If you do happen to find anything better, please, let me know!

Take a look at this: http://www.westonaprice.org/childrens-health/recipes-for-homemade-baby-formula#fcf

Basically WAPF recommends adding cod liver oil and egg yolks to commercial formulas.

My daughter was almost exclusively breastfed/received pumped milk, but there were times she needed some formula supplementation at daycare if I did not have enough pumped milk available. In researching the best product for her, I settled on Nature's One Organic formula and was happy with it.

Most daycares should take pumped milk if you do the bottle preparation for them. If it is not part of their policy, you can request your pediatrician write a note, and most daycares should view it as an dietary exception and allow breastmilk.

I would recommend having backup formula just in case they run out of breastmilk on a particularly hungry day, but overall, pumped milk should work for daycares.

I've just been faced with the same question myself, and after much research have found that either raw goats milk, made in a home-made formula below, or Nanny Care goats milk formula (http://www.vitacare.co.uk/) to be the best option. Goats milk is the closest thing to human breastmilk in its nutritional make-up, but you can also use raw cows milk to create the home-made formula.

We have decided to go with the Nanny Care formula mixed with breastmilk.
