What was your baby's first food?

Like Stephanie, my son's first food was mashes avocado but he hated it. I tried 2 ways in the 3 days, mashed it with, added milk and spoonfeed but he keep smacking the spoon away so it was quite a mess. I also tried BLW method and left chunks of avocado on his tray but none of it went into his mouth. He just squish everything and threw them down lol. But surprisingly, about 6 weeks later, I tried avocado with him again and he took a liking to it
