11 weeks pregnant

11 weeks pregnant + calcium


Your baby's development at 11 weeks

When you are 11 weeks pregnant your baby is set for a rapid phase of growth. A healthy intake of calcium will support their bones as they lengthen and strengthen. Learn how this pregnancy essential aids development in other ways, and which foods to eat for a reliable supply.

Preparing to grow

Measuring between 4 and 5cm3,4 by the time you’re 11 weeks pregnant, your baby is still very small. However, they’re growing and developing rapidly, with all of the bones of the face now in place, fingers and toes separating from their webbed beginnings and ear buds starting to take on a more familiar ear shape1.

Internally, their brain, lungs, liver and kidneys have formed by 11 weeks, but the various body systems will continue to develop throughout pregnancy5.

"Your baby’s development at 11 weeks"

Although your baby has already been making jerky movements for some time5, you’re unlikely to feel any kicks until around 17–18 weeks, or later if this is your first pregnancy6.

Calcium: Building strong bones and teeth for life

Calcium is essential for the normal development of your baby’s bones: it supports the health of your own bones and teeth too2.

Most easily absorbed from milk sources7, calcium has several other important roles8:

  • It regulates muscle contractions, including your baby's heartbeat
  • It helps blood clot normally
  • It contributes to the healthy functioning of muscle tissue and nerves

The recommended daily amount during pregnancy is 700mg per day, all of which should be obtainable from a normal, balanced diet.

"Your calcium requirements don’t change during pregnancy, but it’s more important that you meet your RDA.”

Next Steps

Ensure a healthy calcium intake during week 11 of pregnancy by including the following foods in your diet:

  • Dairy products, including pasteurised milk, cheese and yogurt
  • Some nuts and seeds, especially almonds and sesame seeds
  • Beans and pulses
  • Figs
  • Spinach
  • Tofu
  • Calcium-fortified breakfast cereals and white bread
  • Calcium-fortified drinks such as some soya milks
