I was at a large soft play centre recently that has several different areas to suit children of different ages so all can play safely. My ds (16 months) loves it in the 0-4 section.
Unfortunately some mums seem to think that its OK for their 10 year old children to go rampaging through the same 0-4year section which makes it unsafe for my ds to play on. While I accept that 10 year olds don't need the same level of supervision that 16 month olds do, I don't think it should be my responsibility to ask them to play in the area for their age while their mums drink coffee oblivious.
AIBU?
