Do what feels comfortable for you and your family. Don’t try to speak a language with your child if you are not comfortable or fluent in that language.
Don’t worry if your child mixes his two languages. This is a normal part of becoming bilingual.
Provide your child with many opportunities to hear, speak, play, and interact in your home language.
If you think your child has a speech or language delay, consult a speech pathologist experienced in bilingualism for advice.
