If it were me, I would make my husband care for her, because it would drive me crazy to have sole responsibility for our child's feeding (and sleeping!) beyond the newborn stage. You say that he can't afford to miss work, but you also say that you can't afford to bring her, so both options will cost money, but bringing her would be more stressful to me than having my husband be the primary parent for a bit.
However, in light of the fact that right now, you are the primary parent, you can consider your schools' attitudes for this visit a litmus test for how they'll treat you while you spend several years of your life with them. Also, take heart; babies' feeding patterns change quickly, and it sounds like she's at the age for solids, so stuff will be changing.
