Lyric discussion by Anastasius 

In a broader sense it's the song about our inner child and how we can become a vegetable ("you're a vegetable"), if we don't pay attention to the child inside of us ("If you can't feed your baby - you'll be always trying to stop that child from crying").

"Someone's always trying to keep my baby crying" - people try to hurt him, so the inner child inside of him starts to "cry" and it's a pain. So "I took my baby to the doctor" means he tries to "cure" and get rid of his inner child and it's no fun and fortunately it didn't work out :) And and in the end he's dancing ("Ma makossa") as law4on mentioned.
