Personally I like the way you spelled it originally (Madelyn) because I pronounced the way you described spelled that way & I'm sort of a "fewest letters is best" thinker since she'll likely have to spell it anyway. We struggled how to spell my DD's name and ended up going with the fewest letters possible within reason.
I agree with most of the others that Madelyn is the best spelling. When I saw the name I thought Madelyn instead of Madeline, some people may screw it up over the years, for the most part, I think most people would get it right. It is a cute, girly name!
Neither of my kids have very long names. DD has only 3 letters, and has been writing her name since she was about 3 1/2. The letters in her name are so easy to write! DS is a little harder and it did take him longer to learn to learn to learn to spell and write it.
I like Madelyn!

Thanks everyone! Very helpful. If we for sure go with Madelyn - I will spell it the "common" way then. I am conscious of how names are spelled. My poor little Sophie has problems. I don't teach my kids the names of letters until they are reading well - so they only know them by the most common sounds they make instead. So, when Sophie first started writing her name she would always write Sofe, because she would sound it out! She's better now, but that "ph" combo still sometimes messes her up! She knows that it's suppose to be the "f" sound, but she can't always remember what comes first, the p or the h.
