At the packing shelf in Aldi earlier with DD aged 3 sat in the trolley munching on a banana to keep her quiet while I packed.
Another mother walks past with a little boy who must have only been 5 or so and the mother says to him "Ah you shame my Billy* that girls sat their eating a banana and you're stuffing your face with chocolate making me look a bad mother" then she laughed and they walked off.
AIBU to have shamed her like this? 
will add she didn't see me packing the bags with crisps, haribo and chocolate which will be shared with DD
*obviously not his real name
