👶 Baby Update

Size: A bowling pin

Last week of the second trimester! Baby's lungs and immune system are maturing. Baby can cough and hiccup. The brain is extremely active. Baby weighs about 2 pounds.

💕 What She's Going Through

Leg cramps, heartburn, back pain — the greatest hits. She may feel huge even though there's still a trimester to go. Emotional as the third trimester approaches.

💪 What You Should Do This Week

  • Submit your paternity leave request to HR
  • Take a babymoon NOW if you haven't — last chance for comfortable travel
  • Second trimester is ending — tell her she crushed it

🚫 Don't Say This

You're only in the second trimester still?

Pregnancy is a marathon. Don't make her feel like it's dragging — she already feels that.

🛒 Gear Tip

Order the stroller now if you haven't. Popular models (UPPAbaby, etc.) can take weeks to arrive.

🧠 Dad Hack

Take a photo of her bump at the same angle each week. At the end, you can make a timelapse that she'll treasure forever.
