My baby is three months old and she developed a oral thrush few weeks back. We struggled a lot to feed that time and we were fine in few days. Again she developed oral thrush and I am worried if she will have any issues with feeding like last time. She is sucking her hands lot. Is that a reason for oral thrush. I don't have any cracked nipples. Why thrush is recurring? How long it will take to recover. Using candid mouth paint now.
