We go to lots of parks with our 2.4yo DS. He loves the sandpit and often we take our own spades etc, although sometimes we forget and sometimes go somewhere adhoc and don't have things with us, or go to a new place where we don't realise there is a sandpit.
Now, often in communal sandpits there are various buckets and spades lying around looking abandoned. I always feel free to give these to DS to use, having had a quick peek round for the owner. If after I pick up the spade I can't see anyone looking territorial, I will just give it to him to use. I keep an eye out for anyone coming near us spadeless, so I can quickly check with them whether the spade is theirs, and leave the stuff where i found it when we're ready to go. If I abandon my spade whilst DS toddles off to another attraction and I see someone else using it, I never mind. Just part of being at the park.
Anyway, got a mouthful off someone the other day for using a bucket they'd left in the pit. They'd stuck some paper pictures onto the bucket and one had come off. I'd noticed this before picking up the bucket, which had been laid there a good twenty minutes before DS picked it up. I stashed the paper pic safely and was intending to leave it in the bucket when we left. To reiterate pic had already come off bucket and was next to it. They were REALLY cross about the use of the bucket and obv thought we'd caused the pic to come off.
Discussing with friends today, there seems to be an even split between those who thought I was hideous for using someone else's toys, and those who thought mouthy mother was a lunatic. MN Jury, what say ye?
P.S., I'm not intending to change my behaviour at all, btw, regardless of MN consensus. I love the give and take in the sandpit and have had nothing but positive interactions with other mums and kids re the sharing of toys, save this one incident. This AIBU is purely for information gathering purposes!
