I need help. Baby is 13 wks old. We have history of eczema so wasn’t surprised baby has it too. However, she’s also developed a pin prick types red rash on her body. Dr asked if we’ve made any changes and the only thing I can think of is her milk. DD was solely on pre-made but for about 3 weeks we’ve been alternating feeds with ready made and powder of the same brand. Dr said it could be this and to switch her milk but I really don’t want to if it’s not the milk. The rash is not really getting better or worse it’s kind of staying the same. Could it really be caused by the milk??
