going back to work HELP!!

So my daughter is 2 months old and eats like a 14 year old boy 😒 no seriously I've been trying to build a supply of breast milk for when I go back to work in January but I'm struggling. I'm pumping as much as I can but she literally eats all day so I'll have 2 bottles worth of formula put up and I'll take a shower by the time I'm out of the shower daddy is feeding her one of the bottles. What can I do to help build my supply? I'm constantly drinking water like a fish I eat like I'm supposed to but she is so greedy. She also nurses to self soothe and refuses a pacifier. This is my first time breastfeeding and I really want to be successful. Thanks in advance ladies !
