Avocado and little ones

Li

I try to feed my son avocados on a regular basis because they offer so much nutrition. He has been eating them since he was 6 months old (is now 22 months) but is starting to refuse them. Occasionally I can get him to eat some on toast but not often. He also will eat them in a smoothie. I'm looking for ideas of how to serve them to get him eating them. Any recipes your kids love?
