Re: Going back to work and continuing to breastfeed
I personally wouldn't attempt to nap-wean. Don't borrow trouble from the future- let whoever will be caring for your LO in your absence figure out how to get him down for a nap, when that time comes. He won't expect to nurse from a nanny/daycare provider/grandma. He knows that you're the only one with that particular superpower! If you nap-wean him now, it's just going to cause you both some misery, over something which might not even be a problem.
Anytime you abruptly drop a nursing session, plugged ducts are a possibility. So keep the pump handy for the first few days back at work- you may need to revise your plan, depending on how your body reacts to the dropped session. I doubt you'll need to pump, but you never know!
If you've never been a big leaker, you probably won't have a leaking problem when you go back to work. But, again, you never know. So plan for a leak- maybe wear a patterned shirt or nursing pads for the first few days back at your desk.
After a year, whole cow's milk or goat's milk is an acceptable replacement for mama's milk. If your LO isn' hugely find of cow's milk, try yogurt. When you run out of breastmilk, that is!
