You have not said why you want to wean other than your husband is uncomfortable with nursing. Do you want to as well? The ages you are shooting for are really really young....the World Health organization recommends no earlier than 2 and as long as mutually desired by mom and baby. The American Academy of Pediatrics says a minimum of a year and as long as desired. Worldwide the averages are over 4 years old, and this is including all the moms here who wean even just at a few days old.....
Would you and your husband be able to read more on nursing and the ways it benefits your child? Have you really talked with him about why he is uncomfortable?
I believe the best way to wean is to let the child do it on their own, this does not give the mom any sudden hormonal changes that a forced weaning does and also assures the child gets what they need and want. Every child will wean at different times, but it will be more waht they need.
If you still after educating yourself more about nursing want to wean I would go to a LLL meeting and get help with it, most of the experienced moms there have several weaned children and so know the best way to do it.
The best method I have had descibed to me is the "don't refuse, don't offer" and gradually and with love method.
I am not sure what to tell you about a pumping schedule, I have always worked too, but taken baby with me to work. I think you could cut back on the pumping if you wanted to, but of course not so much that you were leaking all over your work blouses and also not so much that you risk mastitis, trust me you don't want that, I've had it several times when I was nursing our first child.
I will tell you that if you wean you will not sleep near as much and that getting baby to bed will be very difficult, you might read " Night time parenting" for ideas on that.
Nursing for me has been the only way I could make working and having a baby and getting enough rest work, but this book may have some ideas for you...each child is different.
