Changes can also reveal how attached mothers are to their babies

Most of the time these mistakes can be
explained away by extreme tiredness.

Now a study has found that pregnancy does alter the structure of women's brains as they gear up for motherhood.
But there is no evidence it affects memory or other mental functions - so they're still going to have to blame those sleepless nights for their bungles.
Interestingly, the results of the research
suggested that the changes have naturally evolved so that mum can better detect and focus on the needs of her baby, such as "identifying the newborn's emotional state."
The changes during pregnancy cause some parts of the mother's brain to shrink as neural networks become more specialised - and it was found that the effects last for up to two years
after giving birth.
