Moms w/ kids close in age (current or in the past)....Or kids close in age?

What strategies do/did you use to prevent kids from fighting over toys? My kids have plenty of toys to play w/....however when one has an item, the other wants it too….and a fight ensues.

This even occurs w/ large composite toys w/ multiple play areas (think hot wheels track or little people items…)

I have tried taking the toy away for the day, separating them in their rooms, etc.

I need practical strategies. Please!
