34 weeks pregnant

When you are 34 weeks pregnant, your baby’s immune system develops rapidly. You should try to lean forward when you sit down to get the baby into the best birth position.

Week by week stages of pregnancy: week 34

This week, in pregnancy week 34, your baby is starting to develop an immune system to fight off germs as the placenta has been taking up antibodies from your bloodstream.  Babies borrow their mum’s immunity to a whole range of diseases until they can develop their own immunity. If you are planning to breastfeed, their immunity will be boosted through your colostrum and breastmilk. 

Now you are 34 weeks into your pregnancy, your baby will be moving as you move. This is because the back of your baby’s body is heavier than the front, their back will tend to roll toward the direction you’re leaning. They can move to the left and the right if you are lying down and if you are leaning back they may move to become back-to-back.  It is quite common for them to end up in this position if you send a lot of time sitting down for example in a car or on the sofa. 

The best position for your baby is head down, facing back so it would be a good idea to avoid sitting leaning back on a comfy chair or sofa, or sitting with your legs crossed; it is also a good ideas to avoid positions where your knees are higher than your hips. Sitting in the right positions now, in pregnancy week 34, will help them engage properly in the next few weeks. Try sitting so you are leaning forward on a turned around chair or birthing ball and walk around if you are stationary a lot of the time.

At 34 weeks pregnant, you can experience different symptoms because of your baby’s movements. Sleep can be difficult and uncomfortable, especially if it’s combined with back ache and leg cramps. You do need your rest so make sure you’re as comfortable as possible by using pillows to support your bump. Try getting your partner to give you a massage or use warm water or heat (not too hot) to soothe the discomfort.
