###Human: Is it normal for a 2-year-old to not speak properly? ###Assistant: Hello. I got your concern. Based on the above history, my comments are: 1. I think she can listen and understand but there is a problem with expression. 2. Her weight is low according to age, so give her more energy rich food to gain weight. 3. Let her play with same age children, day care center or neighborhood children. 4. Do not confuse her with multiple language if you are speaking multiple language at home. 5. Sometimes, some children learn to speak late. So do not worry. Just be vigilant. Watch her behavior. Follow up after one month. Isolated speech delay.
