Twin Pregnancy Guide: What's Different & How to Prepare

Types of Twins

Identical (monozygotic): One egg splits into two embryos. These twins share DNA and may share a placenta (monochorionic) or have separate placentas (dichorionic). Monochorionic twins require closer monitoring for twin-to-twin transfusion syndrome (TTTS). Fraternal (dizygotic): Two separate eggs fertilized by two sperm. Each has their own placenta. They're as genetically similar as any siblings.

What's Different About Twin Pregnancy

More prenatal visits and ultrasounds (every 2-4 weeks vs every 4 weeks). Higher caloric needs (about 600 extra calories/day vs 300). More weight gain (37-54 lbs for healthy BMI vs 25-35 lbs). Higher risk of: gestational diabetes, preeclampsia, preterm labor, and C-section. Average twin delivery: 36 weeks (vs 39 for singletons). Expect more discomfort earlier — everything is amplified with two.

Preparing for Two

Double the gear isn't always necessary: you need 2 car seats and 2 cribs, but can share a changing table, baby monitor, and many other items. Consider a twin-specific stroller (tandem or side-by-side). Stock extra supplies: double the diapers, double the formula if bottle-feeding. Build a support network — caring for twins is physically demanding and sleep deprivation is intense. Accept all help offered.
