Im wondering why they even have the baby on the show?
		
		
	 
The baby, IMHO, is actually a very useful device on this type of show. At any point, a "need" for the child can trigger a mission or a challenge to the group, forcing them to risk themselves. ( The baby needing medicine makes more narrative sense than Carl nearly dying to get a framed photo) The baby also drove the final wedge between Rick and Shane, giving them both that final push to want to kill each other. The baby was a good device to extend the stay on the farm ( which was in part, a way to save budget. With Sophia missing and Carl in bed most of the time and out of sight, the production had better cost control. Using child actors is very expensive for time. They can only be on set for a limited time each day and week. Particularly so in this case as Darabont did not, as is typical, cast twins for a single role. ) From what I heard informally, the major split in the production was between Kirkman and Darabont, who had different visions for the show. Apparently Kirkman wanted a "24 style narrative" that mirrored the comics. And Darabont wanted more extensive use of flashbacks and wanted at least two major combat sequence episodes to explain the fall of humanity. There was apparently supposed to be three major flashbacks - one with Sam Witwer, the dead tank driver, and the fall of Atlanta, a flashback to Jenners story and an account of how the Atlanta group got together in the first place. Apparently AMC suits said they didn't want a "Lost clone" but Darabont argued, and I think he was right, that there was too many limitations to character development without including some flashbacks. ( i.e. Michonne as a good example. She's far easier to develop as a character with flashbacks than with her current scowling storyline) When Madison Lintz's parents wanted her off the show ( they didn't want her locked into a show with such a minimal role when they felt she could get better opportunities), apparently Darabont wanted to have Sophia disappear, then reveal she was kidnapped, along with other children,by the Governor, who wanted research done on children survivors to see if he could "cure" Penny. Then they could use her as a plot device and close her storyline out with one guest spot within S3. Kirkman apparently hated this treatment and blamed Darabont's casting choices ( not getting twins) as part of the reason why Lintz's parents wanted her out ( the excessive workload for what is typical for a child actor). You can see it in the writing, not just the bad writing, but overall in S2 and S3, that there are several different "tones" and "voices" depending on who wrote the script and who directed the episode. Apparently Kirkman won out in the power struggle because his vision actually offered AMC the cheaper production model over a higher volume of episodes than Darabont and Mazzara , who both pushed for 12-13 episode seasons. ( AMC has two great shows hitting the back end of their runs and didn't expect The Killing, Hell On Wheels and Rubicon to all flounder so badly)  And in Kirkman winning the struggle, it red eyeballed the former Darabont supporters and pushed to drive them off the show. There really is no reason that Nicotero should be directing an episode and Kirkman writing a few of them, they had a superior show runner, they just didn't want to let him see the job done in his own way.
