Do you think they would ever show a baby walker or a baby getting eaten by a walker on screen? The closest they've gotten so far is showing an empty, bloodied car seat in an abandoned car in one of the earlier seasons.
We can see baby zombies on Z-Nation but on this show we cant see yet. But also on the twd universe,babies probably eaten by walkers or bitten and also reanimated. But amc cant show that because it will be gross.
