Kids r constantly fighting over toys. They snatch from each other. Whatever the 1 year old has the 3 year old immediately wants. 1 year old does less snatching than the 3 year old. Does it help to let them have some of their own toys (at the moment I expect them to share everything)? Do I get really strict with the 3 year old (time outs every time she snatches)? Any tips on things that can ease this? Or is it just a sibling phase that they have to figure out between them?
