I've only been in postpartum for 11 months and L&D for only 5-6 months, but in that time this is what I've seen: Largest set of multiples: Triplets Longest gestation: 42+5 Youngest: 13y.o Oldest: 43y.o. Grand Multip: G19 Biggest Baby: 11lb 3oz Not sure about smallest one Biggest EBL: Either 6 or 7L, DIC, kept her uterus!
