If he wants a boy he will go again for one more try.
My DH really wanted a boy to but he always said it would be better to have a girl for his DD from his 1st marriage as she is an only child and the youngest out of all our kids it would be great to have my 3 boys and then the 2 girls and when we lost Abbi we saw how heartbroken his DD was and my mum so i was secretly hoping to have another girl but after everything DH and i went through we just want a baby that didnt have SLO and i was convinced we were having a boy so when the u/s tech said i am 99% sure its a girl we just burst into tears it was like Abbi had sent us her little sister.
Your DH will fall in love with her the moment he lays his eyes on her.
