What's going on this week

A second growth-spurt window is common around this age for many babies, which can briefly disrupt feeding and sleep. It is a normal, temporary phase, not a signal your routine is broken.

Your checklist

Night-shift logistics

  • Ride out a rougher few nights without assuming the routine failed; a spurt is a strong candidate.

Feeding support

  • Have extra clean bottles or pump equipment ready in case feeding frequency spikes for a few days.

Appointments & paperwork

  • No new appointment typically due this week; a good week to catch up on any paperwork still open (insurance confirmation, SSN card arrival).

Visitor management

  • No specific action this week.

Partner care

  • A stretch of extra clinginess or hunger from the baby often means extra exhaustion for her; offer a specific block of relief time, not a vague "let me know if you need anything."
