Discordant size- ...Discordance between siblings may indicate placental inequalities, twin-twin transfusion syndrome, or other problems. These twins differ in weight by about 1 pound (0.5kg); the smaller twin, on the bottom in this photo, weighed 5 pounds and the larger one was over 6 pounds. Hematocrits were checked on both (a routine in our nursery for twins of any size) and were normal. The infants were otherwise healthy and did well. #clinical #peds #discordant #size #twins #newborn
