Probiotic Sweet Potato Puree: WAPF Baby Food

While I’ll always feel a tinge of sadness when I think about Emery’s first few years of health, I’ll always look at it with even more joy – I’m so thankful for the lessons I’ve learned, how quickly I had to learn them, the speed at which I’ve had to learn new skills [i’m normally the queen of all procrastinators, so if we’d had a different situation, I would have never gotten started], and the healing that’s slowly coming from all the hard work.

Another cause for praise is that each kid after her will have a better diet because of it. I’m still learning, but I’ve come so far. After much research, we’ve decided that The Weston A Price Foundation is the lifestyle we’re striving for. It’s often thought to be similar to paleo, but WAPF encourages the consumption of raw and fermented dairy as well as grains, but only when properly prepared. There’s also a high emphasis on organ meats and fermented foods, which leads me to the point of this post – Nourishing my baby with WAPF principals from the start!. 

We attempted Baby Led Weaning with Cooper, but it wasn’t very successful. He couldn’t swallow solids well [I’ll be explaining why in a future post], but he was crazy about food, so I had to roll with it and try baby food even though I had hoped to skip it. Having fresh battle wounds from our experience with Emery, I wanted every little thing that went into his body to be the most beneficial it could be for his gut. Enter Probiotic Baby Food.

I’ve read in the back of the Nourishing Traditions Book of Baby and Childcare that you can ferment baby food, but I needed something that day and couldn’t wait for it to ferment. Instead, I used brine from a carrot ferment to purée some room temperature sweet potatoes. I love packing better gut health into every little bite!

Probiotic Sweet Potato Purée for Babies


  • 1 small-medium sweet potato
  • 2-3 cups homemade chicken stock [enough to cook the potatoes]
  • Brine from a previously fermented food


  1. Dice the sweet potato [i dice pretty small for faster cooking time] while chicken stock comes to a boil.
  2. Boil until soft, about 15 minutes
  3. Let cool on the counter or in the fridge. You need the potatoes to be less than 105* or the probiotics in the brine will be killed.
  4. Reserve leftover stock to cook something else for baby, or offer as a nutrient-dense drink.
  5. Once cooled to room temp, place potatoes in blender, food processor, etc. Add as much brine as you desire, 1-2 TB at a time, until you reach the best consistency for your baby.

Whenever I served this, I either gave it cold straight from the fridge, or left it out on the counter for a bit so it could come to room temp. He ate it well either way!

You could do this with any fruit or veggie! I’m sure different brines would add different flavor combos to each purée – feel free to experiment! If you’re looking for a place to start, this carrot ferment would work great!

What ways do you serve natural probiotic food to your kiddos?
