Hi K. G, one thing to realize is that at that age, "not sharing" is part of their development. HOwever, that said, it sounds like you believe in teaching it (as I did) regardless. I have a just-turned 3 year old and a 16 month old and have been working on the sharing idea with my 3 yr old for at least a year. and of course, now that I have two, I am working on it with my daughter even sooner since she has been taught by her brother ideas like "MINE!" etc. But one thing that has worked for us - especially in play date situations is to recognize that your daughter wants something and then recognize that the other child wants to play with it also, and then ask/tell them that "looks like we might need to count to ten and take turns sharing this toy" and then start a counting-taking-turns time unti they lose interest in the toy. It helps at this point to have play dates with other children with whom parents you are sort-of on the same page so that you don't feel awkward or uncomfortable stepping in and mitigating circumstances with their child. It helped for me that I had a friend whose children are the same age as mine so when our older boys both wanted to play with the same toy we BOTH took this tone with them and so they had consistency across which parent was speaking. hope this helps!!
