Wow Laurie - haven't been on OB for ages, and can't believe your baby is almost due already! Where does the time go huh?
I'm not certain, but I think you can hire that type of monitor (a different brand, but does the same thing as Respisense) through SIDS NZ. Their website isn't working atm, but you could call and ask them about it? 0800 16 44 55
