Your baby’s weight gain is actually reassuring. From 2.5 kg at birth to 4.3 kg at 2.5 months is a gain of about 1.8 kg, which is within an acceptable range. The fact that she is active, exclusively breastfed, and passing urine 8–10 times daily are all good signs that she is getting enough milk.
At this age, many babies become more efficient feeders and may finish a feed in 5–10 minutes. Feeding duration alone is not a reliable indicator of milk intake.
Continue feeding on demand, offer both breasts if she is willing, and avoid focusing on feed duration. Monitor weight gain every 2–4 weeks rather than daily feeds. If weight gain starts slowing significantly, urine output decreases, or she appears less active, consult your pediatrician for an in-person feeding assessment.
Based on the information provided, there is no strong indication to start formula supplementation solely because feeds are short.
