There are at least 2 monsters in "Cloverfield"

The movie "Cloverfield" is a great movie, and one of my favorite giant monster movies. But as it is a found-footage movie, there's bound to be mysteries regarding the film, yielding some theories about it. The theory I'll be talking about is that there are more than one Cloverfield monsters: a baby, and the mother.
 Now, obviously the baby is matured a little bit. He's not as big as the mother, but he's still kaiju-sized. But what are the differences? How do we know that there are more than one?
 In the Cloverfield wiki, the website explains the origin of the mysterious monster in "Cloverfield". It describes the monster as an infant, being woken up from a slumber by a Tagruato satellite.
 Judging from the differences in some of the monster scenes, it seems like the monster seen throughout the city is the baby, and the one that eats Hud (the cameraman) at the end is the mother. That's right, the mother is in the movie.
 We know they are at least slightly different because of the teeth:
Baby:

 Mother:

 Notice how the large fangs on the mother are on the lower jaw, as opposed to the child's fangs, which are on the upper jaw. The skin color on the mother is also darker than the child's. The mother's brain things also look bigger.
 The tail of the mother is also larger. We know this because of the bridge scene. The Brooklyn Bridge is at least 80 feet wide. The tail of the creature that smashes the bridge is at least twice the size of the bridge itself:
 
 But the size of the tail that destroys the bridge doesn't add up to the size of the one we see rampaging in the city:
Look at the tail:

 Also, one thing I noticed is that the monster shown above (the baby) vocalizes more, as children animals do in real life. We see the monster and hear it roaring several times. But the monster at the end of the movie doesn't roar (at least, not when it's on screen). And the monster that makes an explosion in the city at the beginning of the movie doesn't roar, even when it eats people and passes over the store that Rob and the others are hiding in.
 One thing about the movie that has been revealed and confirmed is that the monster drops thousands of parasites onto the city. But is that even possible? based on what we see of the baby monster, not too many parasites come off it. In fact, when Hud watches the news and records it, we even see the monster as some parasites come off it, and it definitely doesn't look covered in hundreds of parasites. And we know that it hasn't previously dropped any, given the shock of the news castors. So the baby we see in the city can't have dropped thousands of parasites. At most, we see it drop maybe eleven parasites, and yes, I'm sure that some were still hiding on it, but the baby isn't big enough to have thousands of barely visible parasites. Remember that these are parasites the size of large dogs. If we are generous and say that the parasites are the size of the missiles and projectiles we see fired at the baby, it still doesn't add up. Next to the monster, the missiles are clearly visible, so with the close viewings of the monster we get, we should be able to see parasites crawling around on it, but we don"t. But the mother, the second Cloverfield monster, may provide this missing link.  
 But one of the biggest pieces of evidence is the damage paths left by each monster. The monster at the beginning (that doesn't roar) sweeps over the store that Rob, Jason and Hud are hiding in. They come out, and find the street completely obliterated, as if it is so big, merely walking trough the city causes major destruction. And, as already mentioned, it destroyed the entire Brooklyn Bridge with one swipe of its tail, indicating extreme strength. But the creature that bit the head off the statue of liberty can't share that exact strength, otherwise it probably would've ripped the whole statue in half.
 And back to the damage path, the baby that we actually SEE rampaging through streets doesn't cause that level of destruction, even when it crashes into buildings and stuff. The carpet bombs actually do more damage to the streets than it does.
 So, here's what I think happened:
 The baby and mother were each sleeping on opposite sides of the city. The baby wakes up first, sinking boats and bites the head off the statue of liberty, while the mother, who has just woken up, tears into the city and explodes the street. The baby spits the Liberty head at the area where the mother is. The mother then rampages back to the water and destroys the bridge. After that, it prowls around the outside of the city, where it eventually meets Hud, while the baby stays inside the city, taking the brunt of the army's attacks and finally, the bomb at the end. The bomb kills the baby but not the mother (but the bombs and stuff do eventually kill it), yielding that code at the end of the movie that says:
SPOILER ALERT
That the creature is still alive.
