New mum here - getting fed up of the generations above me (my mum, DH mum and Aunt) making comments like "we did it in my day and my children are all fine" about things to do with my DD that are now advised against by NHS, professionals etc.
Or the other way around, for example BLW - "all mine had purées and were fine"
What's a good response to this that shuts the conversation down without losing my s*?
