If a 5 yr old (closer to 6, no SEN) spilt a full glass of milk all over a table / floor due to being a bit careless and not noticing that by moving her arm she was going to topple it?
What would you do / say to him or her? And how would you expect him or her to react?
If it's relevant the situation was in a restaurant, not at home. Think harvester or slightly smarter
