FJ I think that a session with a psychologist wouldn't do him any harm. I know he works hard and it may be difficult for him to find the time but I think if he is already anxious about this bub then it may be significantly worse by the time it gets closer to the birth.

Coping with his anxiety must be hard on you some times and maybe suggesting to him that if he goes and talks to someone about it then life may be a little bit easier for everyone, but mainly focussing on how wonderful you want this to be and how you want him to be excited about the bub.

Good luck
