Some of the new baby models are too big/disproportionate

While the new baby mobs are a step in the right direction, some don't look right. Kittens should be smaller; currently, they're nearly as big as adults. Lambs look strange as their heads are too small and flat. Lastly, baby horses are very disproportionate. Their necks are too long, and their heads too wide. They're also just too big when compared to the adult horses. Other babies could also be sized down a bit, but they at least look less jarring than kittens and baby horses next to their adult counterparts.

E: Today, the new Villager babies released, and it's the most disproportionate of them all. Why do they have a square head when V/Illagers are rectangular? Adding one or two more pixels to the head height and nose length would immediately fix this issue!
