After our scan last week we found out we have trizygotic triplets. This means each baby has it's own placenta and no-one is sharing any "resources". This is the BEST kind of triplet to have as it reduces many inter-womb complications, although there are still risks to any multiple pregnancy from prematurity.
The triplets are likely to be fraternal and not identical, however they cannot be sure until birth, whether we actually have one set of identical twins and then another baby, or whether we are having three separate babies. Identical twins are unlikely as we have three placentas present and twins usually share one, but it is not unheard of.
