I think it depends on the age of the kids too. If they are 2 or under, it is really difficult to have them sort it out themselves...they just don't know how to. So for the young ones, I usually let one have a turn and then make sure the other gets a turn soon after (with lots of praise for handing it over). But, if there is a huge scuffle with tears and possible pushing, hitting, etc, then the toys gets taken away. If they are 3 or up, yes, I try to get them to come up with a solution first before intervening. Also, when they are sharing or taking turns well, I always praise them...I find this works better than anything at giving them a good idea of appropriate behaviour.
