@Pertinax This is the assumption in view of the lack of official information. Zoochatters reported one of the Sumatrans carrying what looked like a dead baby on 12 December. Subis and Emma both gave birth in December 2017 but Subis's baby DNS. I've seen recent photos elsewhere of a young orang who was probably Emma's 3 year old, Kesuma. It seems more likely that Subis would have just given birth again.
