Whilst I do agree she should be grateful for the support you offer I do think that your update sounds a bit petty. The things with the sandwich or pens are not 'cutting' remarks. Just simple comments to her son. And yes, you are there to look after him. But regardless of whether you are there, or you are in your home or hers, she is his mother. She is the one in charge of him. Unless she's interrupting you every couple of minutes by telling you what to do with him then I don't see how a couple of little comments (in what is presumably around 2 hours) is really interfering.
I get on well with my MiL but still make the occasional comments like 'don't let DD get hold of that' (she's a toddler) or 'dont give her the chocolate with a nut in' for example. Not because I'm interfering but because it's an automatic response as it's my child. As a pp said it's just mothering.
Where do you think the relationship between you first went wrong?
Angela Rayner cleared by HMRC. What a coincidence!
