I was going to say that about you or DH's feet.
Your friend's bub must have small feet though, cos I think the average is about 7-10cm at birth????? )I'm pretty sure Dr Google could help confirm that though).
My kids both have neanderthal feet (DS is only 15months and already growing out of his 7's). He could never even wear baby 2's.....and their head comes out first anyeho.....
