Daryl takes care of the Grimes family.
Daryl’s stance towards children has changed so much. He was horrible towards Sophia when she was scared in that nursing home. He seemed to consider Carl a nuisance in one part of season 2, as he told Carl “Why don’t you go find your old man? Pester him instead?” Then during “Beside the Dying Fire” when Lori announced in panic that she couldn’t find Carl (when the herd appeared), he immediately turned to her, exclaiming “What?!!”
In season 3, when Rick went emotionally and mentally awol, Daryl was looking out for Carl. First he pulled Beth aside and asked her to keep an eye on Carl while he was going on the run for formula. Then he held Judith and fed her, asking Carl if she had a name yet. When Carl went through the names, Daryl was sad himself (particularly when Carl mentioned Sophia and Carol) but then, seeing Carl’s sadness, he tried to cheer Carl (and everyone else) up by calling her “little ass-kicker.” Then in “Hounded,” Daryl opens up to Carl about how he lost his mother when he was young, trying to empathize with him. Before going to retrieve Glenn and Maggie, Daryl tells Carl that he’ll keep on eye on his father for him.
In season 4 when the infection breaks out in cell block D, the first thing that Daryl is concerned about (and Carol too) is getting children to safety. Later on in season 4, after what happened with the claimers, Daryl comes to Rick with a wet handkerchief so that he [Rick] can wipe the blood off his face. Rick tells him to save the water for drinking, but Daryl’s rationale is that it’s important to wipe off the blood so that Carl doesn’t see it. It’s also interesting how as Michonne, Rick, Daryl, and Carl are walking to Terminus, Daryl is in the back with Carl. He looks back at him a few times and stays level with him in the back while Rick and Michonne are talking. Interesting that Rick himself wasn’t standing back there with his own son (who had nearly been raped the night before) but Daryl was.
