Does anyone have any experience of this? My almost six month old son has been EBF but starting from a month ago had a few bottles of expressed milk topped up with formula while I was out with no problems - about three or four times and no more than 2oz or so each time.
The last four times he has had a mixed feed it has been a different story (major vomiting) and I've finally figured out it is definitely the formula that's the problem all of a sudden. I had thought there was a problem with my fridge and my breast milk was off (even going as far as to buy a new fridge) but last night he had just formula on its own for the first time and was really, really ill, bringing up bile until his stomach was emptied out. It was awful.
The thing is that I can't find any info anywhere where people have experienced the same issues after using formula, people talk about minor digestive issues or a rash, but not puking bile, so I'm unsure if it is likely to be a dairy or lactose intolerance. I've tried two different brands of formula so far but they've both been dairy based.
I'm on holiday at the moment so will go to my gp when I get back but was interested to hear any relevant stories in the meantime! I'm quite happy breastfeeding, but I am going to back to work in a couple of months so will need to sort something out.
He's back to his normal self this morning and happily feeding away on me as normal btw
