I completely understand where you are coming from with them feeling left out ...
DH and I used to have huge arguments about him not wanting to feel the baby move etc. But the minute DS was born DH has been completely devoted ever since.

Try and remember it's easy for us to get that instant bond as we feel and experience everything - as DH once told me - it's just a bump....

I think your doing a great ob ... just keep encouraging and supporting him and I am sure that things will get better.

If you ever need anything let me know.
