Congratulations on having your 3d scan and seeing your little one.

I had a surprise with my first 2 and found out with my last 2. I mainly found out for my last 2 as I needed to know what I was having just given the pressures on myself from everyone (me included) to be having a girl. I honestly can say it didn't change how I bonded with my babies, I didn't bond more or less (we chose not to tell anyone that we know which helps) so whilst we have a name etc it is never said verbally except between DH and I when the kids are in bed. And yes the surprise of finding out at birth is one that you can never beat, seeing what your baby looks like even though you know the gender is special too.

I look forward to reading your birth annoucement and finding out what you little Sprout is.
