I was at a stay & play a couple of days ago, and my dd, 2.7, got on a trike (she's only just learnt to pedal) and rode it round the back of the building. When she appeared at at the other side, another child had magically appeared on the trike and the mother was pushing them both. I thought my dd was ok, so I stayed with my ds, but when I looked around again the mother was talking to my dd. I went over and it turns out that she was trying to get my dd off the trike so her ds could use it. I was a bit miffed by this as we'd only been at the place for 5 mins, and there were other trikes her ds could have used. I also thought it was a bit off that the mother was trying to do it as my dd will of course be a bit intimidated by an adult. I intervened, very politely, and the mother got really annoyed, saying that it would be nice if they could have shared it.
And that's what really annoys me sometimes. I don't think my dd should have to share all the time, especially when there's enough equipment to go round, and she'd only just started using it. I also get annoyed when other kids take her personal toys at the playground without asking and it seems we should just accept this. If my dc's approach anything that's not theirs I tell them not to touch it. To me it's about respecting other peoples property and personal space.
I don't think I'm being unreasonable, anyone else have an opinion?
