My son is almost 5 weeks old. I was given antibiotics during the birth. At 3 weeks, the pediatrician found that he had thrush (only on the tongue) and prescribed nyastatin ointment for him. He said to give it only for 1 week. I did & it seemed like it had gone away for the following week but then came back. Yesterday I started the nystatin again for him & my OB prescribed nystatin cream for my nipples. He latches on for half a minute and then pulls away & the process continues throughout the feeding. He still has the same amount of dirty diapers but I can feel that he is getting less milk. I am feeling really frustrated. I know it will take some time for this to clear but should I also be worried about my milk supply?
