Week 9: your checklist
Quick answer
What should I actually do at about 9 weeks old?
A second common growth spurt window can shake up the routine you just found. 5 concrete tasks below, grouped by what they're for.
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."
