Doesn't sound like Diana will age differently than normal people according to Jim Kouf in one of his recent interviews about the finale/season 4

So we haven't seen the last of the baby? Well, you haven't seen the last of the search for the baby. It becomes a very practical issue. You don't want to go to a child that can't say anything for three scenes when you have so many other things to get to. The action is with the people trying to find out where the child is, not so much with the child eating its first solid meal. '''It's going to be more important when it is about 5. So Season 9 we will get back to the baby.'''

It's hard to say how serious he is because I'm sure there will be more of the baby before season 9... but it sounds like the baby ages normally.
