Neil Matheson, an Aussie cartoonist has had several cartoon books out
that focus on bubs in utero - cute - and an hysterically funny (if you
are a breastfeeding mother) book called "is he biting yet? These used
to be available through NMAA in Australia and Neil has done some
cartoons for NMAA as well.
An enquiry through the NMAA website may bring some more information.
Cheers,
Querida. NT
