Re: 13 month old wont take the bottle
My daughter also started refusing bottles a 13 months. After a year old it's ok if your baby doesn't have breastmilk while she's away from you. You can even stop pumping if you want and it won't affect your supply when you are with her. Lots of moms stop pumping at 12 months. As long as you are nursing when you are together (at least 3-4 times per day) she is getting plenty and it's not necessary to substitute other sources like cow's milk.
Is she eating solids? That should be fine to sustain her while you are away, with a little water to keep her hydrated.
