In March, hubby and I are going on a mini-vacation (without LO) and will be gone for approx 32 hours. I don't think I'll ever have that much breastmilk supply (although I'm trying) and I certainly do not want to feed him formula either. He will be 9 mos, 6 mos adjusted. Is there any alternative? Like a human based formula? I've also heard of using goat milk? Anyone have any ideas? It would be so appreciated!!
