My 2 1/2 year old has been having playdates once or twice a week with a girl who is 1 week younger than her since she was 10 months old. We had and continue to have the same experience. They love to play together but constantly fight over the same toys. When they fight we try not to intervene and let them work it out. If it gets violent than we make the aggressor go into timeout and then apologize and kiss the other when she comes out of timeout. They are just now starting to be able to work things out between themselves without me and the other mom intervening. We both think that it is good to have them play together because they are developing their social skills. Kids don't really have social skills until they are 4 or 5 so fights are going to happen. The best thing you can do for them is to let them work it out on their own and be consistent in letting them know that hitting and biting is unacceptable behavior.
