My boys are wonderful, I actually wanted boys- SHOCK HORROR!! And I could easily have another couple, I have 3 under 4 1/2 so far.
I think one reason you want another girl is the fact that you love your DD so much that you want more of the same, IYSWIM? Trust me, when the baby is born it won't make any difference what gender it is.
I don't want to turn this into a thread that defends boys, I easily could! My boys are obsessed with Charlie and Lola, all sorts of role play. DS1 reads his school books and like doing sums and mazes, but his main obsession is teddys and his baby brother. DS2 likes cooking, baking and CARS. Boys are human beings, wonderful cuddly creatures who need lots of love and mothering. They are fun and funny, adore their Mummy. What you see is what you get, they are honest, not superficial.
I also think it's easier to keep boys on the straight and narrow as they get older if you get them into sport/football/karate etc.
I am so lucky that I will have every Saturday afternoon to myself while DH and Grandad takes them to the football!
I feel so so lucky to have 3 lovely boys, all different but wonderful. Don't make yourself ill with the thought of having a boy, you will love him.
The main worry I have as a Mother of boys...and I can already see it at DS's school, is that girls can belittle boys and this carries on even when they become men. Boisterous boys can be seen as naughty boys, rather then 'playful'. FGS some of the comments on here are derogatory, I really hope my DS's don't get this sort of thing, boys can be very sensitive.
Sorry, going OTT now!
