There is still chance, but you got to be very hardworking. Last time I only express breast milk for 2 days for my baby when he is on hospital due to jaundice. After reach home I was discouraged by mum n grandma to breast feed. At 3 rd week I was super regret. Went to see lactation con for help. In the end I pump 3 hrly day n night without fail. you can also try motililium or fenugreek to help in increase supply.
I suggest you get ready a good electric dual pump. The qty you can pump out might be very discouraging but you must persevere, Best is if you still can latch on your baby then supply will increase faster. your baby might get very frustrated because there is no milk. Lactation con also suggested me to buy a supplementary nursing system, it works by hanging a bottle of milk around your neck, n a tubing where one end place near your nipple. This is so that while baby sucking your nipple there is milk come out, to prevent baby from getting frustrated while you can let him suck n stimulate.
I bought that but in the end never use it because i decided to go for exclusive pumping so that other ppl can help me bottle feed. Let me know if you interested to try n I am willing to let go at cheaper price. Is brand new.
Breast milk is really the best we can gv our baby as mummy. Strive on hope you can success also.
