Take a look at the DateAdd function. Using it, there are 2 ways of doing it, depending on your form structure and the result you want.
If the [DateAdmitted] control is bound, meaning that you are storing the [DateAdmitted] value in your table, then on the AfterUpdate event for [Birthday] put the following code...
Me.DateAdmitted = DateAdd("yyyy",3,[Me.Birthday])
If you are not storing the [DateAdmitted} value in the table, and the [DateAdmitted] control is unbound, you can set the control source of the [DateAdmitted] directly by putting this as its control source...
=DateAdd("yyyy",3,[Me.Birthday])
In either case, set the format property of the [DateAdmitted] to whatever you want to see. If you want to see a short date, select that from the drop down box. If you want a full date, type mmmm dd, yyyy in the format property.
