Your baby

The face is becoming more recognizable, with a small mouth and tongue. Major organs, including the heart, brain, lungs and kidneys, continue developing, and early bone formation is underway. Hands and feet are taking shape. These changes are gradual; a weekly summary describes a stage of development rather than a checklist that can confirm an individual baby's health.

Your body

Hormonal changes may bring nausea, tiredness and altered tastes or smells. A meal that sounds appealing in the morning may be difficult later. Smaller meals or snacks may be more manageable than a large plate. Try to notice which foods you tolerate without turning every meal into a test. Tell your care team if you are struggling to eat or drink enough.

Eating when tastes change

Make a short list of foods you can usually manage and ask about alternatives when your usual choices are unappealing. Our pregnancy food guide explains preparation details such as pasteurization and cooking; it does not replace advice about your individual nutrition needs. Mention any restricted diet, food allergy, ongoing vomiting or supplement you cannot tolerate. Your clinician can help you decide whether additional nutrition support is useful. Seek medical care promptly if vomiting prevents you from keeping fluids down rather than waiting to discuss it at a scheduled visit.

A little context for these comparisons

These are approximate sizes for each week, not measurements of your baby. Babies and produce both come in different sizes, and the illustrations are not shown to scale.

Before week 20, length is measured from head to bottom. From week 20, it includes the legs, from head to heel. That change explains the jump in length between weeks 19 and 20.

When to get help

Seek medical care right away for warning signs such as a severe or persistent headache, vision changes, chest pain, trouble breathing, severe belly pain, vaginal bleeding, leaking fluid, or thoughts of harming yourself or your baby. These are examples, not a complete list. If you cannot reach your care team, seek urgent medical care. Call 911 for a medical emergency.

About this guide

Approximate measurements and development information draw on the NHS weekly guides. Linked US health resources support care and preparation topics. The topics are suggestions for discussion, not a schedule of required appointments or tests. Your own care plan may differ.

Every pregnancy is different. Your care team can help you understand your baby’s growth and any symptoms you’re experiencing.
