@nearlyamummyof2boys yes I have been getting it, I find it happens more when I have a busier day and on my feet more. I don't remember it with DS.
Agreed about babies and bottles. We didn't buy too many of any specific brand of bottle at the start for that reason, you just don't know which ones baby will take to.
That and I was planning to exclusively breastfeed so didn't think we would need many (if any) bottles, but I had low supply so he was dual fed.
