I just cut it up in slices with the skin on and gave it to them from 6 months. They eat the flesh and discard the skin. The skin is useful for holding on to it, otherwise it is too slippery for them. No need for mush. DD loves avocado so much (still does at 2.5yrs), I used to joke she was 50:50 avocado and breastmilk till she was a year old!
Lemon stops it oxidising, it will go brown without. It's not great defrosted as it goes very watery. You should just eat them yourself in bacon and chicken sandwich. Also you don't need to mix avocado with milk as they're very soft, like banana in texture.
So I thought I was doing really well, getting some mush made and frozen in preparation for Operation Solids in a couple of weeks.
I picked up a couple of reduced avocados today, thinking to mash then freeze, But when when I got home, the weaning recipe book says avocado mush can't be stored and needs lemon juice? (won't that curdle the breast milk I'm mixing it with?)
Can I do anything to store them? I don't like avocado, and thought I was being all clever, giving her lots of tastes
