(Failed) Attempts at Sharing
At this age, your child is able to remember peers and show preferences for other children, but she is still what the child development experts refer to as ego-centric. The world revolves around her. For this reason, she still may not understand concepts about sharing.
When there are conflicts over toys, describe to her what is happening. "Allison, Eric was holding and playing with the cup. See how upset he is because you took it. Let's give it back to him and find another cup for you." She is interested in playing beside peers but still hasn't developed the skills to play cooperatively. This will be a big year for her to learn about the feelings of others, develop the important skill of impulse control, and use language to communicate with her peers. If she is not in childcare or around other kids her age, try these tips for starting a playgroup.
This is an exciting (and sometimes trying) time for you and your child. Hang in there! You both have much to explore, enjoy, and learn from one another.

As you're considering your child's development, keep in mind that all children are unique. Whether your child reaches milestones early or late, she has her own developmental path to follow. The dividing lines between these months are very fuzzy. If you have any concerns or questions about your child's development, please check with her healthcare provider.
