Anyone know about cravings???

[LeBe]

Wondering if anyone can help. I am currently 32 weeks pregnant and have developed a really big craving for sponges. I have looked up on the internet about possible causes as some people have told me it is due to being deficient in something, but cant find anything.

Try googling "Pica in pregnancy"

My sister in law had this craving too. She carried around a bathroom sponge in her handbag for the last few months of pregnancy and kept taking it out and smelling it.
