I think after seeing episode 4, the odds that Miles is baby chang have increased greatly.

Daniel is jumping through time, along with everyone else in the remaining group. I think in the two hours between the moment he talks to Desmond and the moment he gets back to the beach with the rest of the survivors (when Sawyer asks him where he's been the last two hours) might've been the time he was checking out the excavation of the wheel. We don't really know exactly what time in history they are all in anyway.

So, theoretically, it can still be Miles. Miles the baby, as opposed to Miles, the adult on the beach.

If you guys haven't seen the Marvin Candle video from the San Diego Comic-Con, you should take a look. candle gives us his "real" name, and tells us that the video he is recording is being transmitted through a pinhole that is 30 years in the past. You can hear the baby crying in the background, and Candle tells someone to take the baby outside. He gives verbal proof of speaking to the future, by giving information about current events, like the internet and George W. Bush.

The kicker: The voice of the camera operator (and probably the person who supplied Candle with the information about the future) TO ME, sounds like Daniel Farraday. Maybe this took place during Farraday's two hour absence as well.

Bottom line, the baby can theoretically still be Miles.

Because Daniel was there via jumping back through time?

I have to disagree about the baby being Miles. Soon after his Dad, Marvin Candle went into the Orchid where they were trying to break through the wall, they show Daniel come in dressed as one of the workers. Now him and Miles can't be that far apart in age so how can the baby be Miles?

What if the only people who can conceive and carry to term are those that were born on the island? Maybe anyone brought there can't carry to term?
Also, if Miles and Charlotte were both born on the island, why is Charlotte being effected by the time travel and not Miles? I don't think that baby is him... Watch me have to eat my words next week! haha!

I don't think that there were problems conceiving or birthing children on the island until after the time travelling was established. The wheel was not dug up yet, so it didn't pose a problem. I also think the baby is Miles.

Claire's baby (Aaron) was conceived off the island and born (healthy) on the island. Same with Danielle's baby (Alex).

Jin and Sun's baby was conceived ON the island, but left the island before too long and was born (healthy) back in Korea.

The only pregnancy problems we've seen are with women who conceived AND attempted to carry the baby to term on the island.

Also, as Atomictk said, the only pregnancy problems we've seen were with Others/Hostiles/Natives; we have not seen any Dharma folk or Losties actually exhibit symptoms, have we? (That's not to say they would or wouldn't -- just that we haven't seen any evidence yet.)

Mothers couldn't come to term with babies on the island, right? Or was it that they couldn't be conceived on the island? Or was it that mothers and babies don't survive the birth process?

If "baby Chang" was brought to the island as a baby already, and not born on the island, maybe he would have just been immune to the whole thing, like everybody else.

It did seem like the early stages of the Dharma program, as well. Maybe they didn't know how the island would affect people, let alone babies brought to the island. Maybe what happened to the baby is the reason they changed policy about who they eventually brought to the island.

To further add to what DaveJohnson said, I don't think it has ever been established that the Dharma folks have fertility problems. That was only the Others I think.

Just a note - it's not that the Island has a problem with babies being born on the Island, but with babies being conceived on the Island. Chances are Chang's wife came to the Island pregnant, just as Claire did...

That was the 1st thing I thought of too. Was the baby born on island. If so, I wonder if it all changed when Ben took over.

I think this has to be Miles. I can't think of any other key Asian people that have a significant tie to the island...that are older. Did Sun's father seem to have any interest in the island?? I know we were all speculating that him and Widmore might be tied in together.

The 'children' of Lost always seem to have some gigantic stuffed animal related to them. Panda, shark, giraffe, to name some. Is this important? Or, just set decorations? I do think this is Miles born before the incident. So is he looking for his birth place too?

If it is Miles as a baby, then we know that he, Daniel and Charlott had all been to the island previously when they were picked to go on this mission. So what about Naomi? Do you think she had been previously, or was she just part of Keamy's crew? How did Widmore know they had all been before?

I agree that it's going to turn out to be Miles. I thought of that when I watched The Barracks video when there was a baby crying in the background and Candle said "Can't you keep him quiet?" or something similar to that...

So IF Miles was the last baby born on the island, and he has this "speaking to the dead" thing going on, did the island impart powers to babies born there? What would that mean for Aaron?

oooh! I think you might be right!

I think this might turn out to be MILES
