At the beginning of the 16th week, your body will expand and change in size and functionality. It is possible you might feel some butterflies inside. In the starting, this might feel like gas, bloating or muscle twitch, but a few weeks from now the baby movements will be evident. But whether you feel it or not, the baby is definitely moving in the 220 ml of amniotic fluid.

By this time, you will be sporting a baby bump as the uterus continues to expand to reach its peak. As you have already entered the second trimester, you would be adding around 400 grams a weight to your body.

The second trimester is sometimes called as ‘honeymoon phase’ as emotions even out, symptoms like nausea and vomiting subsides and you are back on energy levels. This week you may also feel more sleepy than usual along with unusual food cravings. While experts don’t know the exact cause of craving, they blame it on hormones.

The delicate skeletons of the baby continue to harden. Around this time, the baby would be sucking her thumb or kicking the amniotic sac. The legs are also growing quickly and soon you will start experiencing kicks from inside.

Size, weight and appearance

By the time you enter week 16, your baby has grown up to 5 inches long or the size of an avocado (butterfruit/makhanphal). With the continuous growth spurt, the baby should be weighing around 100 grams, almost double the size of last week.

Healthy eating

The well-being of your child is highly dependent on the food you eat. While many women might have overcome the unusual cravings or aversion for food and smell, some might still feel the same. Irrespective of your situation, healthy eating should be on top priority. Below list of foods should be in your diet schedule this week.

Expecting dads

If you haven’t figured out your baby’s name, this is the right time to do this homework. Take out a list of your top favorites and compare that with your wife’s. This important because once you start spreading the news of your pregnancy, many people would ask what you are going to name your baby.

And if you choose to answer these queries, you would perhaps be subjected to various opinions. It is a great idea to work upon the names beforehand as it will let you gently shun the opinions of your friends and relatives no matter what their intention is.


This week is the time to get back to your doctor’s clinic for the next appointment. This prenatal visit is a crucial one as you will go through several tests including:

  1. Urine test for checking gestational diabetes and preeclampsia
  2. Blood pressure
  3. Measuring weight as well as checking fundal height, the distance between your pubic bone and the uterus
  4. Testing amniotic fluid (amniocentesis) for checking chromosomal abnormalities

Tips for the week

As you visit your doctor this week, you will get a bunch of tips to follow. You might be advised to start sleeping on your left side as lying flat on the back in the third trimester might cause shortness of breath. A large blood vessel (vena ceva) which runs along the right side of the spine could be impacted by the uterus and weight of the baby, affecting blood supply.

So the best way is to roll over the left side and place a pillow under your belly and another one between the bent knees. This will support your back and alignment. Besides, don’t forget to add low intensity exercises such as swimming and walking. Also think positive, stay hydrated and get plenty of rest.

A through idea of what you can expect during this phase will always keep you ready to face the challenges you might encounter during pregnancy.
