I'm 26, will be 27 when baby is born. DH is 28 and will be 29 when baby arrives.
Our second as well, we were 25 and 27 when DD was born.
Incidently- DH and I, and my sister and brother all have January birthdays, DD has a February birthday (was due in January) so this little baby will have the odd birthday out. Honestly, I'm glad, too many Christmas time birthdays!
