      16 weeks pregnant

      Constant cravings

      Even though you may only feel light flutters within your belly, your baby is becoming active and moving around more. Internally, your baby’s major body systems are becoming established by the time you’re 17 weeks pregnant. Vitamin D still forms a crucial part of your pregnancy diet to support your baby’s bone development.

      Hand movement in week 16 of pregnancy

      Around now, your baby may start flexing their arms and fingers. Their hands may even be able to meet, form a fist, and hold each other1. As your baby’s nervous system continues to develop, their range of movements will also progress1.

      Their hands may even be able to meet, form a fist, and hold each other.

      By week 16 of pregnancy your baby’s eyebrows and eyelashes are also starting to grow, and the eyes themselves can make small movements from side to side2. While they’re beginning to make facial expressions, they can’t control them yet1.

      Strange food cravings

      Be it iceberg lettuce and cold boiled potatoes, or ice cream with gherkins, unusual food cravings aren’t uncommon in week 16 of pregnancy. Some believe they are due to hormonal changes, or a need for specific nutrients3. However, despite much research and the experience of millions of pregnant women, there’s no scientific evidence to support these theories.

      As long as what you crave isn’t harmful, you can go ahead and eat it – in moderation. Just try to maintain your healthy, balanced diet too.

If you think you may be experiencing pica cravings, speak to your midwife.

      Feeling the squeeze?

      It will soon be time to shop for maternity clothes. Until then, here's a tip: If you're struggling to fasten your jeans, thread a hair band through the button hole, then hook both ends over the button. It should keep your waistband together but make sitting down a little more comfortable.
