Continuity mistake: The Galactica can retract her launch bay pods into the hull. She is shown doing it just before her first FTL jump. The instant before she jumps, the pods are suddenly shown in the extended position again.
Revealing mistake: After Dualla shoots herself, Gaeta hobbles back into the room. While the effects people made sure his real lower leg was erased from view behind his upper leg, they forgot to remove the shadow of the lower leg being cast upon the steel floor. The shot then changes away and returns to find the shadow has now been fixed the second time we see it.
Chosen answer: Her motives are never explained. One possibility would be curiosity, a simple experiment in human infant physiology. Another, perhaps more likely one from her subsequent look of apparent distress is that it was, in an odd way, an act of mercy, giving an innocent baby a swift death, rather than leaving it to die in the nuclear fire or of radiation poisoning afterwards.
