Do you and your wife speak the same language? You and your wife should talk to your daughter in your own language(s). Your daughter will be a little confused, but after a while she will understand.
Don’t worry, she will survive to the mix of languages. The main examples is Catalonia in Spain. Almost 100% of the people speak Catalan and Spanish for historical and political reasons. The kids grow up without problems, speaking both languages.
Your daughter will be a native English speaker. (The native language is the language they use in kindergarten.) She will use the English sounds to speak in your language and the pronunciation will never be perfect, but enough to talk.
Don’t worry too much. Just speak naturally and your daughter will learn.
Get some movies with English and your language(s) audio and subtitles. Play the wathc the movie in the different language. (With small children, the problem is not to repeat the movie, but to repeat it only a few times.) My daughter loved to see the movie mixing the audio and subtitles in different languages. (I hope you don’t have problems with the DVD zones.)
Books are also good. I try to buy her the books in the original language when it’s available and she can understand it, in spite she sometimes don’t know a word and has to use Google to translate it.
Also, start with comics. The story is simple, the text is short, and she will get a lot of information from the sorrounding drawings.
Learning earlier is easier, and will be helpful for the future.
Happily I married a Finnish woman, and we've agreed we'll use both languages all the time. (Helpfully I'm also learning Finnish at the moment).
The (local) people I've seen do things seem to either repeat words in both languages, or speak solely in English one day, and "foreign" the next day.
I'm not sure which is best, but I'm looking forward to finding out :)
