When is it ok to start milk?

My son will be one next month. He is breastfeed and will occasionally drink breast milk from a bottle. We are going camping the week before his birthday. I was thinking maybe I could start whole milk a little earlier (of course still nurse him, mostly at bed time). Anyone think this is okay offer should I just wait before introducing him to while milk? Tia
