Packing Hospital Bag

Chantel
Hi ladies, 
I'm currently 36+2. Starting to get baby's bag ready for when I go into labour and am actuallyfreaking out about what size clothing to pack.
The hospital has said that this baby will most likely remain on the smaller side. They don't seem to concerend though! 
My first born was a whopping 10lbs (4.53kgs) but this baby is measuring in at 4lbs15oz (2.24kgs). 
What size clothing should I be packing for baby? I have some 00000 (5), 0000 (4) and 000 (3). But I'm worried if I pack each size I'm going to be walking in with a suitcase! 
Any advice or tips would be muchly appreciated!!
