I add a little formula
Immersion blender, add water as needed
I just use a blender from Walmart. You can get a cheap one for $20 or so. I just add water/breast milk to make it thin enough to mix well.
Get on fb marketplace and find a used Beaba. It steams and purées, easy to clean and has an awesome blade. I got one for less than $50, also check shopgoodwill.com
There’s one being auctioned right now that ends in 29 minutes listed for $9, get it!!
I use nutribullet baby blender and use breast milk
Add water or breast milk for consistency
