Yeah, kid walkers is going to offend some folks. Kind of like how they are in a pickle with baby Judith, simply cannot show her getting eaten or turning into a zombie even though that'd be close to the scariest thing they could do.
I think the lawn thing is part of why they are in the woods so much. I'm sure at times it'd make more sense to cut thru neighborhoods and walk down streets to limit surprise walker ambushes and rummage for supplies, but in reality that would be much harder to film and in WDead land that possibly exposes them to people ambushes. Of course if no one is cutting thru neighborhoods then the ambush crowd would wait in the woods, but that kind of over-thinking is misplaced when watching WDead.
