congratulations and good luck with the screaming. my advice is simple. know that he will make mistakes and love him because of them not in spite of them. let him make them because then he can grow. always help him back up, but do let him fall.
oh and get him swim lessons at six months. the sooner the better, before he has a chance to be afraid. go to a swim america school. they have great instructors. *pats self on back*
