Hello mommies i have a question. So when my baby was first born my milk didnt come in until almost a week after having her. I would put her on my boob as much as i could and pumped but she just didnt/want to latch on most of the time its been awhile since ive put her on the boob but i still have milk but im not to sure how much but they do feel full at times. I really did want to breastfeed is there anything i can eat drink whatsoever to help ny supply grow again other than latch her on. Reason why im going more towards it now because shes been on 3 different formulas and all of them has made her sick. She throws up clumps and she is constantly throwing up and i know my milk will be good for her..

Please help with some knowledge. Or is there any breast milk banks in san antonio that i can buy some or anything?
