Congratulations on your baby girl!
Man, this girl is a lot harder to design than it looks OTL
Once your JBDs' baby hatches, you can:
a) Keep it. If you and another person bred your JBDs, it is up to you to decide who will keep it. Remember, the baby counts in the 4-JBD-limit.
b) Give it for adoption. Hold a contest to find a new owner for the baby.
c) Gift it to someone. You may gift the baby to another user.
