A pregnant woman tell us about her experience , and says that other people like her family and friends tell to her about she have to and not to eat , many people think the baby is from public property and hurts the feelings of her..
Nowadays are confussion with some aliments like peanuts, raspberries, honey, taramasalata, liquorice, lettuce, coffee, chamomile tea, macaroons, seafood, all oily fish, sausages, chillies, sweetbreads, kidneys and health drinks.
people in other places tell her about not eat aliments like sauces because have arguments like the baby can be alergic in the future.. or simply because they hear to other people talk about that.
