She is a step ahead if she is beginning to learn many words and is interested in learning to read in her first language. You can help by supporting her in her first language as she learns English. Talk with her, read with her, encourage her to draw and write. In other words, do the same kinds of activities mentioned before, but do them in your child's first language. When your child first enters school, you may want to talk with her teacher.
Schools welcome such talks.
Teachers even have sign-up times early in the year, though you may usually ask for a meeting at any time. If it will help, ask a relative, neighbor, or someone else in your community to go with you. When you go, tell the teacher the things you are doing at home to strengthen your child's speaking and reading in her own language. Let the teacher know how important this is to you and ask for help. Children who can switch back and forth between languages have accomplished something special.
