Breast milk is best for your baby

Breast milk is best for babies. The World Health Organisation (WHO) and Health Promotion Board (HPB) recommend exclusive breastfeeding for the first six months of life. Unnecessary introduction of bottle feeding or other food and drinks will have a negative impact on breastfeeding. At around six months of age (but not before 4 months), infants should receive nutritionally adequate and age-appropriate complementary foods while breastfeeding continues for up to two years of age or beyond. Consult your doctor before deciding to use infant formula or if you have difficulty breastfeeding.

Abbott Singapore fully recognises breast milk’s primacy, value and superiority and supports exclusive breastfeeding as recommended by the WHO.

The HPB recommends that infants start on age-appropriate complementary foods at around 6 months, whilst continuing breastfeeding for up to 2 years or beyond to meet their evolving nutritional requirements. If no longer breastfeeding, toddlers can switch to full cream milk after 12 months. This should be complemented by a good variety of solid foods from the four main food groups (fruits, vegetables, grains, meat and alternatives).

4th Week of Pregnancy


Baby's Growth and Development When You're 4 Weeks Pregnant

This is it — the week you’ll likely miss your period and find out you're pregnant!

By your 4th week of pregnancy, your baby probably has embedded in your uterus and is growing at an amazing rate. Here’s what’s going on at 4 weeks pregnant:

  • When you’re 4 weeks pregnant, your baby’s body now has three distinct layers from which all of his organs will develop.
  • From the 3rd week of pregnancy to the end of the 4th week of pregnancy, your baby grows to the length of the head of a pin — about 1/25th of an inch long.

Your Changing Body at 4 Weeks Pregnant

Four weeks into your pregnancy you've missed your period. Time to test! You might be eager to find out if you have a little one on the way. Learn more about pregnancy tests:

  • Your home pregnancy test measures a hormone (hCG (human chorionic gonadotropin)) that your body produces after a fertilized egg attaches to the wall of your uterus (usually six to 12 days after fertilization).
  • Most pregnancy tests recommend waiting to test until at least the first day of your missed period.
  • The longer you wait after your missed period, the more accurate the test will be.
  • Testing too early could result in a false-negative reading of a still-developing pregnancy.
