What's going on this week

By around three months, many families report more predictable naps, more smiling, and a workable rhythm forming, though every baby's timeline varies. If a return to work is happening this week, treat the first few days as a real adjustment for the whole household, not a switch that flips cleanly.

Your checklist

Night-shift logistics

  • If you're both back to a work schedule now, rebuild the overnight rotation around it explicitly rather than letting old habits linger.

Feeding support

  • Settle into whatever the ongoing feeding logistics look like post-return (pump schedule, bottle prep, or both) and keep your part of it consistent.

Appointments & paperwork

  • Check that the SSN card and birth certificate are both in hand and filed somewhere findable; you'll need them again for tax season and school enrollment later.

Visitor management

  • A good week to revisit visitor rules now that routines are more established; loosen them if they've been serving their purpose.

Household & gear

  • If a return to work just happened, do a supply check: enough bottles, formula or milk storage, and diapers on hand that a bad week doesn't turn into a supply-run crisis.

Partner care

  • This is a good week to name out loud that the hardest stretch is largely behind you, and to actually thank each other for it.
