SIL had her baby (unplanned pregnancy but wanted and the same number of months as many of us have to prepare) in hospital last week and MIL is furious with all the staff on the ward.
Her complaint? That “they” expected SIL to look after her DD but “SIL knows nothing about babies and no one showed her what to do”. 
She says that DD was left crying
until another woman on the ward told SIL that she was probably hungry and to feed her. From what I gather someone had shown SIL earlier in the day how to prepare a bottle etc. but then left her to it, SIL had “forgotten” what to do and thought someone would come and do it again.
There was another incident with a nappy but I haven’t had the full story. It sounds like someone snapped at SIL but again “poor SIL” didn’t know what to do and had to ring MIL who left work to come and sort things out.
SIL didn’t go to any classes, read any books or even ask for advice when in hospital. MIL says she “didn’t like to”.
It’s been a week and MIL is still mad telling everyone and anyone how bad the hospital was. She even angrier now than when DN was first born.
She’s being unreasonable isn’t she?
