How long does a typical sixteen week growth spurt last?

Usually a few days of noticeably increased feeding. If feeding goes back to normal within about a week, a growth spurt is the likely explanation.

How can I tell a growth spurt from the sleep regression?

If increased hunger is the main change and feeding goes back to normal quickly, it is likely a growth spurt. If naps and night waking remain disrupted for weeks, it may be the regression.

Should I change feeding strategy during this time?

Offer feeds on demand for a few days if your baby seems hungrier. Small, frequent feeds can be easier than forcing long gaps.

When should I contact a healthcare provider?

Contact a provider if your baby shows poor feeding, very low wet diapers, weight loss, high fever, or extreme lethargy. Those are reasons to check in.

What simple sleep changes help during a regression?

Keep bedtime routines consistent. Use calm wind-downs and short, regular awake windows. Small, steady routines help more than big changes.

How long does the 16 week growth spurt last?

Usually a few days of extra hunger. If feeding settles but naps and nights stay unsettled for weeks, that points to the four month sleep regression instead.
