They seem rather baby-ish...though it's a fun concept to play with, we get to see Kate outside of being just a baby, and Pal outside of just being a dog- basically a new perspective on some characters that typically don't play a significant role in episodes. For some reason I liked the original "The Secret Life of Dogs and Babies" and am okay with re-watching that...but the others, I sort of feel ambivalent, except for "Fifteen" but only because of the other two subplots involving George and Arthur.
So I guess I'm okay watching them for the first time or so (watching "Baby Steps" right now, an episode I've either never seen in its entirety or just forgot), but they're not typically episodes that I'd probably go back to watching...or watch again if they aired on TV as reruns.
