our 15 month old gets a reliably satisfying sort-of-custard-like breakfast: coconut milk kefir (homemade from kefir grains), raw egg yolks, cinnamon, a little apple sauce for sweetness, and also some frozen berries (mostly wild blueberries which are lower in sugar), etc. She's stopped enjoying avocado unless its mixed in with other things.
Snacks will be things like pieces of gouda cheese, Coconut Manna - I highly recommend the Nutiva brand, kids and adults go nuts over it. Fat is satisfying. During other meals and as occasional snacks she gets sweet potato, usually dowsed in ghee or coconut oil.
She also continues to get some raw goat milk via bottle to supplement a low-ish supply of breastmilk.
I would like to eventually reduce the animal dairy in her diet to be on the safe side, but I figure for now things like quality hard cheeses and quality raw goat milk are not the end of the worlddoing more good than harm.
I have to admit I also score her some pieces of my 99% dark chocolate, accompanied by Coconut Manna or slightly dipped in my bulletproof coffee (!) and she LOVES it. Which got me thinking, apart from the chocolate, how to get her magnesium in her diet without supplementation.
