What's happening this week

Three little faces are just beginning to emerge — dark dots where eyes will be, soft dents where ears will form. Each one still has a small curled tail, a leftover sketch that will fade away over the coming weeks.

For now, they each have their own quiet little world to drift about in, three separate pockets of fluid, blissfully unaware that they've got company just next door.

Three little wonders this week

  • Three tiny brains are busy building themselves at a startling pace this week.
  • Little buds are turning into paddle-shaped hands — fingers will follow soon.
  • Umbilical cords are up and running for all three, delivering everything they need.

The triplet twist

Your bump is already behaving like a pregnancy several weeks further along than the calendar says. Don't be surprised if your usual waistband gives up the fight before you've even told a soul.

Something to look forward to

  • In about 3 weeks, all three officially graduate from tiny embryos to proper little fetuses.
  • You're about 5 weeks from the end of the first trimester.

To Mom:

Your three little blueberries are each growing their own unique features, and your body is already softening and changing to keep them safe. Trust in your strength as you navigate these early changes—you are built for this.
