SIL and BIL recently had first baby six weeks ago.
Visited them. Am a non-smoker and not ill - no colds, sniffles etc.
Baby was not prematurely and has not health issues.
Held baby and kissed him on the cheek, as you do. SIL reacts very strangely and BIL says "We are asking people, apart from us and SIL's mum, not to kiss the baby."
The reason is that SIL heard of a case where someone kissed a baby on the face and the baby had a massive allergic reaction and died.
Am happy to respect their wishes - it's their baby- but AIBU thinking this is further evidence that something may not be quite right with SIL?
In the past BIL has told me that if she feels she has eaten too much, she feels sick so that she will go to the bathroom and make herself throw up. He seems to think this is quite normal. She also has issues with cleaning.
