anyone have one year old EBF who still has CMPA?

unless a dietitian has asked you to reintroduce dairy then i wouldn’t have started

if she successfully completes the milk ladder with consuming solid food then fair enough but until then you may be triggering her allergies by allowing her to have your breast milk containing traces of dairy

As above, you need to discuss with the dietician. Milk ladder needs to be done with the baby as they can consume solids. Reintroducing dairy via breast milk is not advised as you have zero control over how much cows milk protein she's being exposed to. My 13 month old has tried the milk ladder once and failed, now waiting to try again soon. It can take years to outgrow it.
