Hello... in such circumstances it’s always better to give the breast milk which can be expressed before hand. Approximately baby should have 120 -140 ml of milk every feed. As mentioned by my colleague it can be saved up to 24 hours in the fridge.
Next Steps
If that is not feasible, then u can use either of nan pro or lactogen 1 with the concentration of 30 ml per one scoop of the milk powder. So that will be 4 scoops in 120 ml of boiled and cool water.
Health Tips
Use infant bottles from companies like Phillips or pigeon which is easily available on Amazon. Hope this helps. Kindly give a feedback if my solution helped you. Kindly consult if u need my advise regarding the well-being or ur baby. I wish him best of health. Take care.
