Just found this at Notch's blog site:

This seems like a good update. This might be what happens when you breed animals or might just be a common occurence? Will this be the death of the Baby Animals mod? I'm glad that we can have baby animals but i'm still wondering if they will even be worth it... Maybe they will have small creepers that can only blow up one block or two. Or an enderman that has trouble teleporting. Would the baby animals be agrressive ever? Would they be able to grow up to be adult animals?(probably by use of bonemeal?)

Please let me know if you have any ideas on this by commenting below. i would be glad to answer any questions or such... Can't wait for 1.9!
