New Giraffe?

Is there a new baby on the way for April and Oliver?  Will Tajari have a new sibling in 2019.  Afterall she carries for 15 months which means that would be right after Christmas 2018.  The vet has cleared April for another pregnancy and Oliver got the green light, so will she be showing soon?  At her age I am sure they are concerned for her health, but guess we will see in a few months as to whether we are on baby watch or not.
