I have a 2 year old DD and just found out today we're having a little boy next. Am v excited but, silly as it sounds, a bit flummoxed about the family dynamics when you have one boy and one girl! DH is one of three boys and I am one of two girls - and oddly most of my cousins and friends are also same- sex siblings. If you have a DD and a DS do they get on? Do they have any common interests?! Is it as lovely as having same sex siblings? I am sure it is but coming from no experience of it would love to hear your stories.
