My DD was born on 2 January so it was quite warm. I had singlets and jumpsuits. I only took 1 outfit to hospital, a going home outfit. But the hospital provided her singlets to wear everyday and she was wrapped most of the time. My DD was 4kgs (8lb 14oz) so never fit into "0000" size really. Was in "000" size for a few weeks but wasn't long and she was fitting into "00" size.

HTH...good luck with everything!
