confused which is the nub???

[Holz]

I can work out which one is the nub on the top pic is it the thing near babys bum or is that too low? And on the bottom pic is it the thing sticking up in the air or is that babys leg bone? Totally confused :/

Im not a pro but I think its the bottom pic one and I would guess boy. The one on top does look to low to the spine I think.

You can see the nub clearly on the bottom shot and it looks very boy to me
