First, I don't know if this is only in Japan - I have never had a baby in another country, so my experience is limited. I know the UK would NEVER hand out something like this...
We received this when we went to get a scan and check-up.
For those whose Japanese isn't up to scratch, it divides the pregnancy into 3 parts and displays what positions are OK to have sex in.
I love the fact that they just had to draw pictures too.
Also, I still can't work out why EVERYONE in Japan will swear blind that a pregnancy lasts 10 months.
