Week 16

Mum

A good way to connect with your baby is to give the bump a gentle massage. It’s safe to do after the first three months of pregnancy, and it’s soothing for both you and your baby. You may want to use an oil or a cream, particularly one aimed at reducing stretch marks, but avoid aromatherapy unless it’s one of the safe oils (check with a reputable aromatherapy specialist).

Dad

Last week, we talked about lifestyle choices. This week, we’ll continue the thread and concentrate on your health. If the pregnancy is progressing smoothly, the best you can do for both of you at the moment is to get some exercise together. Walking is a fantastic way to get moving, and generate some of those much needed feel-good endorphins, plus it has a calming effect on the state of your mind. You might like to do pregnancy yoga with her, but if she’d prefer some time alone, go for a swim or get a mate to smash a squash ball around with you at lunchtime. Mood-boosting guaranteed.

Baby

Hey, you are the size of an avocado pear this week. You won’t believe it, but your heart is pumping blood at a rate of over 20 litres a day. That’s like 20 bottles of milk. How do you do it?

Photos in the bumpandbaby.co.nz/week-by-week/ are by Lenart Nilsson. Lenart's series was bought to fame when his photo, considered the greatest photo of the 20th century, appeared on the cover of Life magazine in 1965. “Everyone interprets images differently, depending on their social, cultural and religious background. In the digital era, I believe it is more important than ever to go back and take a look inside ourselves. What better way of doing that than with these photos?” ~ Jane Stene, art gallery director and curator of Lenart's definitive black and white series, told the The Guardian in 2019. It is Lenart Nilsson's wish that his images are never used for political debate about pro-life.
