Emily • I'm 25 years old and this is my second baby I'm already a mummy to a lovely little 5 year old boy :)
Hi just looking for some advice, I really really love pate its something Iv been craving for ages some people say it's ok to eat some people say it's not ok, do any of you know any advice on this? Have you eaten it and been fine? Do you know the reason pregnant women can't have it??
