That's a wonderful way to introduce solids to a young baby. He gets a taste, he has a fun experience, and the solids don't replace breastmilk in his diet. You might want to search the solids forum for threads on baby led solids or BLS. In a couple months, when your baby is ready for solids, you can skip the spoons and just let him self-feed.
Regarding solids, DS has gotten really interested in watching us eat for the last month. He gets especially excited when I am eating apples. Sometimes I have let him lick the apple just to get a small taste of the juice. He likes doing this....is it wrong to do this? He really just sticks out his tongue and touches the apple and then gets all giggly and excited.
