Yes - I've been in the US for almost 30 years. I started speaking to my kids in my native language from birth after almost 20 years in this country (my husband now understands most of it, never having formally learned the language). It still does not come easily - because so much of my life plays out in English. Indeed, sometimes I need to look up a word in my native language

So what! Be proud of your daughter and speak to her in your language. You will both benefit, and you will both feel more comfortable over time. Also, watch some TV in your native language if you can - for my European language, a lot of the channels are available online. Good luck, and take this opportunity!
