Technically this isn't their first solid food. At 2 months old they had a taste of our soft-serve ice cream and a week before this we gave them a piece of our pancakes to chew on. This time we prepared ahead of time.
I bought a few avocados that were rather firm and let them ripen on the counter for a few days. Since we are trying Baby Led Weaning there was no need to mash it; the girls did a fine job mashing it in the little fingers! They really liked it! They ate most of the big slice I gave them. One thing I was not prepared for was the mess and how extensive it would be. But just look at those beautiful messy faces!
