This may read like a MIL bashing thread, but please bear with me because I promise it is not intended to be.
I get on well with my MIL and think she is great. She stays with us twice a month to look after DS - this is something she wants to do and brings her a lot of pleasure. It also means that I have come to realise, and have subsequently shared observations with a close friend of hers that she has very disordered eating. I won't say she has an eating disorder because she has never had that diagnosis, and I think she 'manages' her condition so that it never quite becomes critical, although it appears that it may be a contributing factor to some long term health conditions she has.
Over the past couple of months I have noticed that her eating has become increasingly restricted. She goes through periods where it seems to improve and she eats more normally, and then periods where it worsens.
On the latest time she arrived with us she complained that she had eaten a dodgy egg sandwich on the train on her way, but since she has been here all she has eaten is a little porridge, a dry cracker and some scrambled eggs.
The reason I'm asking for opinions, and I'm prepared to be told IABU, but on the few times I have had food poisoning I have been unable to eat the thing that caused it for several months afterwards. I certainly couldn't have eaten it whilst I was still feeling ill. Is this common or can other people happily eat the same food stuff that recently made them ill?
I am asking because I am concerned about MIL's eating habits, and don't know whether to add this to the list of reasons to be concerned or whether it is nothing abnormal.
