What's happening this week
This is the singleton finish line — the date most pregnancy apps are built around. Three babies sharing one womb almost never stay in this long, and were never expected to.
This page is here purely for context and a little comparison. Your triplets' true finish line came earlier, and arriving earlier was always the plan, the good plan, the healthy plan.
Three little wonders this week
- A single baby at 40 weeks averages a lovely armful; three babies at that size together would be an extraordinary amount of baby all at once.
- Hardly any singleton babies actually arrive on their exact due date.
- The longest known triplet pregnancies land around 37 to 38 weeks — 40 weeks was never really on triplet radar.
The triplet twist
Every standard pregnancy app is built around this week. Yours never was, and that's exactly the point of this one — your finish line arrived at 34 to 37 weeks, and getting there was the whole beautiful goal.
Something to look forward to
- If you're reading this after your babies have arrived, this is where the calendar ends and the wonderful rest begins.
To Mom:
You've reached the final finish line, and what a journey it has been. Whether your three are already snuggled in your arms or about to make their debut, you have been the most wonderful first home they could ever have.
