Does Doti replace a doctor?

No. Doti helps you understand and prepare, quoting from doctor-reviewed content or trusted health sources and showing the source. For signs that need checking, Doti always advises seeing a doctor.

Where does Momby's information come from?

From content reviewed by doctors at Momby, and from sources such as Vietnam's Ministry of Health, WHO, UNICEF and major hospitals. Each article lists its sources. Vaccine and check-up schedules follow how things work in Vietnam.

Is my family's data safe?

Your book and diary are private by default; only the people you invite to your baby's profile can see them. Momby does not sell personal data and does not send health data to advertising tools. You can delete your account at any time, in the app or on the web.

Can my partner and relatives use it with me?

Yes. Each person has their own account and joins your baby's profile through an invitation link. Whatever one person logs, the whole family sees.

Which stage is Momby for?

From the day you find out you're pregnant through your child's early years. The book, reminders and diary follow your baby through pregnancy and the first two years; milestone articles go up to age 5.

Does Momby cost anything?

Logging, the book, reminders and sharing with family always work in full. A few Doti questions are included each day; Momby Plus is for families who want to ask more and is bought in the app.

Where can I use Momby?

On your phone (iOS and Android) and on the web. On the web you can read the weekly articles, see your book and timeline, and ask Doti; quick daily logging is easiest in the app.

What are normal and abnormal nuchal translucency measurements?

Updated 8 Nov 2026

In babies with chromosomal abnormalities, heart defects and many genetic syndromes, the nuchal translucency is thicker. Nuchal translucency measurements are classified as follows:

Normal nuchal translucency:

- 2mm for a baby at 11 weeks.

- Under 2.5mm for a baby at 12 weeks.

- 2.8mm for a baby at 13 weeks.

Abnormal nuchal translucency:

- Nuchal translucency over 3mm: Risk of Down syndrome.

- Nuchal translucency of 6mm: The baby is at risk of Down syndrome as well as other birth defects.

- Nuchal translucency of 3.2 – 3.5mm: High likelihood of the baby having Down syndrome.

Note that the nuchal translucency ultrasound only correctly identifies 75% of the risk of Down syndrome. Depending on the nuchal translucency result, you may need further non-invasive screening tests such as NIPT, the Triple test or the Double test, or invasive testing such as amniocentesis for a more accurate diagnosis.
