I've done it with both my kids. More with the second. With my son I started him with steamed broccoli. With my daughter she started on strawberries as it was in season hahah. They tried different foods like pasta, pizza (homemade), banana, steamed veggies.
I love this method as it teaches babies to chew before swallowing rather than swallow before learning to chew, making it less risk of choking. They may gag a bit...but that depends on baby...my daughter naturally gags a lot even when she was exclusively breastfed.
It does take a bit of time before they actually eat anything but that's ok as food isn't so important at that age
