Baby updates

Posts – Got a story?

Your baby is the size of a lemon.

Your baby is able to make a variety of expressions and work out her facial muscles. Her kidneys will be producing urine that will be released into the amniotic fluid surrounding her. You may also spot her sucking her thumb when you have an ultrasound.

You’ll also see her neck and her arms will be more proportioned in length with her body. Her liver will start producing bile, while the spleen helps to produce red blood cells.

Mummy updates

Your energy levels will be up, although the nausea would have subsided together with the soreness in breasts. Your tummy will also be showing slightly more obviously.

Week 15

Baby updates

Your baby is the size of an apple.

He is beginning to develop the air sacs in his lungs and his legs will be growing longer than his arms. He can sense light now, even though his eyes remain closed. This is also when his tastebuds are forming. For parents who are excited, this is the week where baby’s gender will be clearer, though it depends on her position when you do your ultrasound.

Mummy updates

Your weight gain might be slightly more by now, compared to previous. Don’t be alarmed if your nose feels stuffed up or your experience nose bleeds.

Week 16

Baby updates

Your baby is the size of an avocado.

It’s the beginning of a spurt of growth for baby over the next few weeks. Her legs are more developed and her head will be more erect than previously. Patterning of the scalp will begin, though locks may not be recognisable. The amount of blood her heart pumps will have increased.

Mummy updates

The top of your uterus will be halfway between your public bone and navel, with the ligaments that support it thickening and stretching as the uterus continues to expand. You will be able to feel your baby move from this week onwards, though for some mothers, they may only feel it at 20 weeks.

Week 17

Baby updates

Your baby is the size of an turnip.

His skeleton is forming a more definite shape, while the umbilical cord is growing stronger and thicker. His sweat glands will also start developing now.

Mummy updates

You may feel that your centre of gravity has changed due to your growing belly. This may cause unsteadiness in your feet, and you may be more prone to falling. Do take extra precaution when moving about. Your eyes may also become drier.
