HI K.,
My daughter also loves computer but she is 3 and she actually learned fast when it comes to the mouse. SHe goes on website like NOGGIN,PBS,and her favorite barbie.I have them saved in the computer so she knows which website to go to. I think its best for you to get her,her own lil laptop computer. They have a couple for her age.I was going to get one for my almost 2 year old son I beleive it was a v-tech, for 24.99 in walmart.com.It has a lil mouse keyboard a small screen,games,music plus learning activities.Check it out and see. These kids now a days are very fast learners,we think they wont understand but look at my daughter everyone is amazed when they come to the house and see how she goes to the website and plays her learning games.Hope i was helpful. Take care.
Sincerly,
D.
