COngrats on your firends bub!

3kg is an awesome weight for 35 weeks

I probably wouldn't bother with the prem nappies, 3kg isnt really that small I'm not sure that the prem nappies would even fit. My lil man was 1.5kg and went straight into huggies newborn, they had to be rolled down and adjusted to fit him, but they did the job. I also wouldnt bother too much on 5x0 items, at 3kg she wont be in them for very long.

As for things for mum, you seem to have a good selection of things, the most important thing right now is your friendship, someone to talk to, someone she can call at awful hours during the night if need be.

All the best i hope your friend is home soon.
