Cruising with Child (ren)
Here''s a book that may give you some insight. Some of what is said in the book seemed to me to be common sense...but that being said one persons common sense isn''t always common. Book is called Babies Aboard written by Lindsay Green copy 1990 isbn 0-87742-273-7
Best of luck to you. My wife and I are planning to begin our 15year or so trip in November w/ a 2 year old and a 2 month old so we were happy to find this book.
