Actually, I'm fairly sure that IABU, but need to process my crossness.
I will start by saying that my MIL is completely lovely, I get on very well with her and she has a lovely bond with 14 month old DS.
The story is that she is a very experienced, but now retired, health visitor. She said that based on some photos of DS that she thought he had a slight squint. Neither DH or I could see it, but we were prepared to defer to her professional experience, as was my own HV and GP. So DS had a referral to the eye unit at the hospital today, which resulted in me having to hold my precious baby as he cried whilst he had stingy eye drops placed in his eyes and frightening lights shone in them. And then had to put up with blurred vision for hours afterwards.
He doesn't have a squint. I knew that.
I just feel cross at her that he has had to go through all that for nothing. I'm sure she was acting out of concern for him but it was only through scrutinising him and his photos in detail to look for the slightest thing amiss. If she hadn't been looking for a problem it is not something that would have been considered by anyone else.
Please tell me that IABU and to get over it!
