Solids

My baby is three months old and I've decided to start solids a month early. The reasons why is because he's already teething, he holds his head up well, he's already more than doubled his weight from birth, and he shows an extreme interest in foods. Also he isn't ever full from his bottles. I've fed him solids in his bumbo seat and he knows how to eat from the spoon and loves the food. He opens his mouth up wide for the food. My question is has anyone else's baby started on solids this early?
