Baby is at an awkward angle but the tip looks round and detached like a boy!

3D image can't see any gender clues. Can't see any visible nub on second pic and third pic, due to angle and baby looking a bit twisted don't feel confident to guess. Sorry no help here.

I meant to add this one as well. Thank you for looking just grasping at guesses here-really hoping for a boy this time!

I was going to say boy based off the skull. Good luck!

Looks boyish to me!

Thanks ladies-gives me some hope!

I think the one thing that has me convinced it might possibly be a boy is the skull-I mean that jaw is very masculine! I'll be scared of this turns out to be a girl with a head that massive! Lol

[Thorz300]

I think boy based only on skull!
