All About the Pelvis

Your pelvis is a wonderful thing, and it plays a crucial role in birth!

Your pelvis is made up of three bones – the ilium, the ischium and the pubis. They are joined together by the coccyx at the bottom of your spine, and by cartilage. It’s important to be careful of the pelvis during pregnancy because it’s a support structure, so too much flexibility can affect the rest of your body.

Now, the hormone relaxin makes these bones more mobile during pregnancy. You will have lots of relaxin in your system in the 3rd trimester in readiness for birth. Relaxin helps the joints to move and flex to accommodate your baby, and it helps your pelvis to move during childbirth. Your pelvis expands by 28% in labour due to relaxin, and this helps your baby to make their exit smoothly!

Your baby’s fontanelles - which are the soft parts of your baby’s scalp - move and slide over one another to mould the head while moving down the birth canal, and your pelvis is able to flex and move as this happens.

Remember that after birth, your pelvis will have been through a lot, so be kind to yourself! Make sure you rest but also if you feel up to it, gently move your pelvis. Swimming and gentle yoga are the perfect exercises to start with!

There are so many ways to stay in control of how you feel during labour, and understanding the way your body works is a big one. There’s insight into this and so much more on the butterbean blog. Be sure to keep reading!
