I agree with wisewoman. I also think MIL needs to butt out.
My son is going on 20yo, but when he was little, she was a good grandma to him and all, but was and still is a controlling person, so needless to say I dealt with some nonsense, and then I eventually told her, of course as nice as I can, that she needed to step back. She tried to almost replace my position as mom, even convince my husband I didn't know what I was talking about when it came to some nutritional/health concerns, again cause she was a nurse, blah,blah, and she knew.
See, she kept on me about my being what she called overly protective, to be careful in malls,especially when lots of abductions occur, I was wrong, she said "don't worry" nothing will happen, etc.
As she started to see local news and regular news she said to me, "wow, now I know why you worry, it's good you are protective". She thinks some things are like in the past, when my son was an infant, she wanted to give the kid some honey, we told her it is very dangerous to an infant, that there is a bacteria, that is alright but when the immune system isn't fully developed yet, etc. you needed to wait till the child is a year old? I don't remember exact age, but we were cautioned by pediatrican, MIL thinks she knows more, she's a retired RN. I told her do not even think of it, she had to be snippy and say, "oh, that is nonsense, we all had honey, and we didn't die".
My husband finally saw this, with her, and called her aside and said, "no", when the baby is at the "safe" age for this, then we shall let him have it.
Whatever she is feeling, let her get over it, don't upset yourself for not choosing to go on today's trip, next one that comes,you may want to go then,but do not fret about today's choice.
Take care now,
Roe
