We have found out with all three of ours so I can only say YES it helped me bond with the girls before they were born (one still baking). It also helped me on ALL three occasions get over the "Its not a boy" thing as I have always wanted a baby boy.

We didn't have any 3d scans as I was worried about seeing roughly what the baby looked like. and not having any surprise if that makes sense??

Why don't you get the scanner to write on a piece of paper the sex of the baby and put it in an envelope.That way if you REALLY want to know you can take a look but if you're still undecided then you can choose to leave it until you have thought more about it.
