Congrats from a will-be-a-third-time-dad-within-the-next-month!
At least you did it right for your wife--she gets to be pregnant during the winter, and give birth in either the winter or spring (depending on how far along you are). Right now, my wife is really NOT enjoying being 8 months pregnant in the July heat! She much preferred the first two times, both of which were born in April. (It also helped that the first two times, she had either zero or one other kid in the house to keep up with. Keeping two of them from accidentally killing themselves or each other, all while pregnant, is far more daunting.)
