Congrats to your friend.

I honestly wouldnt bother with clothes just yet. Bubs more than likely wont be able to wear normal baby clothes for a wee bit yet. Brendan (30 weeks) didnt get to wear clothes until he was out of the isolette, that was at just over 3 weeks old. I'd check with the NICU first, as hospitals have different standards ect.

Def a diary, really wish I had one.
Also batteries for her camera?

A petrol gift card, or if shes travelling on public transport some bus passes or soemthing?

All the best to your friend.
