My son has diaper rash ever since I start giving him EBM. I'm not sure is it due to poor handling of EBM. I have low supply, thus I will consolidate the whole day supply to freeze end of day or leave in the fridge for next day consumption. Wonder is it the way I handle causes bacteria to enter and causes my son having poo poo all day.I used to latch on thus he shouldn't have any issue with breast milk.Any mummies encounter this? My son butt now super red T_T
