thanks ladies for all ur comments, I think we may end up getting one as our house is two story (its the old beachcomber style, on stilts IYKWIM) so would be very handy when doing washing and outside.

thanks for mentioning the brands & styles you have 2 - the movement one sounds great, i think we would greatly appreciate that piece of mind considering this is our first bub and we will probably be up checking every 5 minutes anyway!!

thanks again - some great reading
