My bet is on a boy, it might be a silly old wives tale but this pregnancy is so different to M's and it makes me wonder if thats because its a little boy!
Just because of this comment I think you are having another girl because I was the same, my pregnancy with DD2 was so different to that of DD1 that I really thought I was carrying a boy but nope another girl... I was happy anyway I love having two girls close together and secretly would love another

Anyways... I am so excited for you, I cannot wait to hear the news .
