In supermarket today with my parents and 2 DS aged 3 and 4months. A Mum was shopping with similar aged children. Older child having huge tantrum and screaming the place down. Poor Mum looked very upset and embarrassed trying to calm toddler and get out asap. Lots of people tutting and making unhelpful judgy comments. Really wanted to show support but didn't want to seem patronising (we've all had this haven't we?!) and was packing parents shopping at time. How or what could I have done other than smiled in what was hopefully seen as 'I feel your pain' way?
