What's happening this week
Blood vessels in three sets of lungs are getting ready for that very first breath, whenever it comes. They can hear well enough to startle at a loud sound and to know your voice from anyone else's.
You're standing right at the doorstep of a big week. Every single day between now and next week is quietly, meaningfully working in your three's favour.
Three little wonders this week
- Their skin is still a little loose and wrinkled, waiting on the plumping fat that arrives in the third trimester.
- Hearing has come along so well that a loud noise can make all three jump at once.
- Every extra day they spend snug inside you right now makes a real difference.
The triplet twist
Triplets tend to be a little smaller than single babies at the same stage, which is exactly why your scans measure each one against curves built just for multiples, not a one-baby chart.
Something to look forward to
- Next week is the big one: the viability milestone.
- About 5 weeks until 28 weeks, when the outlook keeps climbing.
To Mom:
Take a deep breath and give yourself credit for how far you and your babies have come. Every single day is a victory, and you are building a beautiful foundation for your three little ones with every heartbeat.
