It is highway robbery sometimes I reckon. I have brought most of my mat clothes from baby shops etc and found that while yes, they are expensive at the time, I am wearing stuff this pg that I brought for my first pg. So they better stuff seems to last a lot longer than the tops etc I've brought at BigW and other department stores.

Another thing you could buy is a belly Belt, a piece of elastic with fabric inserts to use with your normal pants/jeans etc.
