5 Amazing Things Our Body Does During Pregnancy

  1. Your baby will let you know when it’s ready to meet you

As babies are growing in the womb, their lungs are full of amniotic fluid and they breathe through the placenta and umbilical cord. As they have this support system in place, they can prioritise developing all the other bits of their body before they need to be able to breathe air by themselves. Around about 32 weeks, as their lungs are completing their growth, they begin produce a chemical called a surfactant – essentially what we all have in our lungs that stops them collapsing as we breathe. Scientists found out that this surfactant chemical is what provides the signal to the mother that the baby is ready. When it accumulates to a high enough volume, it acts as a signal that labour can start, usually from 36 weeks onwards.

  1. Boys and girls receive different compositions of breast milk

True fact! Milk for girls is higher volume with more glucose and calcium. Milk for boys is lower in volume with more fat and protein. Researchers also think that hormone levels differ too which would make a lot of sense. Right from the beginning boys receive more cortisol and growth hormone, fuelling their larger physical frames.

And finally: Dad’s hormones change too

Just before a new baby arrives, Dad’s testosterone levels drop and prolactin (a natural bonding hormone as well as the one that produces milk) is increased. One theory is that it prevents men looking for a new partner and instead prompts them to look after their current one and new family – plus cope better with the potential short term lack of sex…Not bad hey?

Looking at this list, I find it really hard to believe that anyone could think that nature doesn’t have our back and that our bodies haven’t been designed to be anything other than amazing. Of course, it’s brilliant that we can access full medical care when we need it but, women, we can really afford to be proud ourselves too.
