I had 2 teeny babies, Tom just under 5lb and Sam 4 and a bit Llbs when we got him home
for Sam mum cut up a towel into tiny terries
and we didn't bother with wraps until small wraps fitted him (he was 3hrly fed and I had to change him before feeds to wake him up and inevitably straight after so a nappy never lasted more than 90mins anyway
) Tom had small prefolds nippered and I wool soaker of Sams that I shrunk
until smalls wraps fitted him.
