Measurements are approximate. Healthy babies grow at different rates.

Baby development

Vocal cords have formed.
The fetus begins developing a sleep schedule that may differ from yours.
Reflexes are developed enough for sudden sounds or movement to cause a startle.

Your body

Shortness of breath, snoring, heartburn, restless legs, or carpal tunnel symptoms may appear.
Hair may feel thicker and movement may be easier to recognize.
A glucose screening test may be scheduled around this stage.

This week's checklist

Ask your insurer or local service about breast-pump access if relevant.
Research current safety guidance before choosing a crib, stroller, carrier, or car seat.
Notice your baby's emerging movement pattern without comparing it with someone else's.

Call your care team

Call for bleeding, fluid leakage, regular painful contractions, fever, or a clear change in your baby's usual movement.
Seek urgent help for severe headache with vision changes, chest pain, fainting, major breathing difficulty, or severe abdominal pain.
