Re: supply dwindling; time to give up pumping?
You can quit pumping right around a year old and there should be no problems with your supply when you are with her. Lots of moms here quit pumping at 12 months and go on to nurse for many more months or even years. Your supply at this point will regulate to provide milk only when it's needed. I nursed frequently at night and on weekends even after I stopped pumping.
Depending on how often you pump you may want to stop gradually, cutting out one session at a time, but you could also just stop and keep your pump with you in case you get painfully engorged (that can lead to plugged ducts or mastitis, which you definitely want to avoid).
You can try giving cow's milk as a replacement, but it's not nutritionally necessary if you are still nursing 3-4 times per day. Also if she is eating a well balanced diet of solids you shouldn't have any problems.
