With LO it didn't really hit DH until our first U/S at 7 weeks. I think it's going to be the same this time around, except we won't be getting an U/S that early this time so it may take him longer. I think what he can't see he can't really imagine, if that makes sense. I think even for me it was a bit hard to grasp until it could be seen. At what point, or how long did it take your DH to really get excited about your pregnancy? Or for it to sink in that it was real?
