Baby Bottles are used to turn baby animals into adults, anywhere from 2 to 17 bottles may be needed to finish growing the animal. Using a bottle on an animal starts a 15 second timer before you can use another.
Players may "Ask" for bottles from friends, and asking does not share a timer with building resources or ingredients. If a friend has turned one of their animals into an adult you may click on their post to receive a bottle, as well - this does affect your gift limit timer.
Bottles may also be purchased from the General Store for Farm Bucks , in packs of 2 ( 3 Farm Bucks), 5 ( 7 Farm Bucks), and 10 ( 10 Farm Bucks).
