Bring data, not memory

Your logs answer the standard questions precisely: feeds per day, night stretches, tummy-time minutes. The doctor-visit sets in Ask compile your open questions — export before you go.

Is this normal for your baby?

FirstWeeks answers with your baby’s age and today’s log in mind — with pediatric sources attached.

Questions worth asking

Anything sitting in 'Worth watching' cards you weren't sure about; the timing of starting solids for your baby; what the doctor wants to see before the six-month visit; any asymmetry or preference you've noticed.

The sleep conversation

If the four-month sleep shift has started, describe the pattern in numbers from the log — 'waking every 90 minutes since Tuesday' gets better advice than 'sleep is terrible'.

After the visit

Log the vaccines in Medicine with any reactions, note the measured weight and length in Measure — your growth history builds itself from here.
