My bub was/is being tested for a milk protein allergy because his father is LI and my bub has reflux and was fussy feeding at about 9 weeks. We saw a paediatric dietician on the advice of the paediatrician. I was told to cut out all dairy products until he is 4 months old. I had to take calcium supplements to ensure me and my bub was getting enough calcium. I have just introduced a 200gm of yoghurt a day (for 3 days) to see if he reacts. I've had no reaction to that so now I eat as much dairy as I want to see if my bub reacts. I have also just introduced yoghurt as a solid (he has just started solids at 4 months) which is his second food to see if he reacts to that. There really was no rush to introduce yoghurt but given my BF issues the dietician wanted to see which type of infant formula he might need if I stop BF or my supply drops.

I was told it takes a minimum of 2-3 days for the dairy to exit the BM and 20 minutes to enter the BM.

I highly recommend a paediatric dietican if you want to discuss your diet in terms of BM and how to introduce solids when the time comes.
