Just discovered a website called Babymad.com and didn;t realise there was so much on offer and so cheap!
Was about to buy some OVsticks, but found out there are cassettes too, and wondered what the difference was between the two of them, except for price and that professionals use sticks.
Also, would it be worth me buying a thermometer? And if so, why is there one for about a fiver and the other costs £20?
