She does not look very pregnant in this photo which was taken a month or so ago though in others I've seen her lying with legs stretched out etc which is often a position adopted by a pregnant gorilla.
I would expect her(hopefully)to have a straightforward birth and good maternal instinct like her halfsister 'Buu' at Chessington with Mbula- since they have had the same upbringing/good social experience. When Mjukuu was still quite little at Chessington, she would often carry her younger siblings around, always a good sign too.
