💡
Twins rarely hit milestones on the exact same day - and that's normal. Track divergence here without panicking. Your pediatrician cares about the window, not the race.

One twin might walk first. The other might talk first.
Both are yours. Both are exactly on time for themselves.

Being a mom of twins is harder than being a mom of singletons. Full stop. This tab is for you.

How are you, mama?

Log a partner / grandparent handoff

Every hand that holds a baby is a win. No guilt. Track who helped and when.

One win a day

Tiny. Stupid-small. Doesn't matter. Showered? Win. Both babies napped at the same time? Huge win.

Twin mom truth:

"You are not behind. You are not failing. You are doing the work of two mothers in one body. That's not a metaphor - that's biology. Rest when you can. Accept help. Forgive the mess."
