I just had a look and it looks like an adult go card would work quite well for you and DH if you didn't go in together (for visits I mean), maybe one could go in the morning and the other in the arvo and whoever is home sorts out kids...

I think premmie bubs usually stay in hospy until they are equivalent to 37-40 weeks gestation... depending how well they do - little brother was born at 33 and home at equiv. 36 weeks. It can also sometimes be an option to get them transferred to a closer hospital to your home.

Time to get a car seat fitted shouldn't change that much given that even if early, baby will be in hospital until close to when he would have been full-term anyway - so getting a seat early is a bit redundant.
