PLZ HELP

my baby is a month old and when she hit two weeks my milk production wasn't high enough for her so I had to start supplementing this Memorial Day weekend went to my in-laws and forgot pieces to my breast pump so I couldn't pump and I didn't breastfeed her enough while I was there and after I got home by milk production has hit the floor I can barely get an ounce out anyone out there who can recommend anything to get my milk production backup like really good cookies anything I can use to get it back I really don't want to be straight formula I would much rather just be on full breast milk but if it doesn't happen I'm okay with that but I love to have some kind of breast milk in her diet
