Barb - Gabby had her first bath the day after she was born and I was expected to bathe her every day (I guess for practice). I think sometimes it depends on the bub's temp. If your little one was in special care, it may not have been possible to bathe her for a few days.
Gab was in special care for the first day and a half but, yeah, she was ok to have a bath the day after. Neil gave her the first bath as per my family tradition. My Dad bathed all of us for the first time. It was soooo cute to watch and he did a brilliant job!
