You got good advice from Cheryl on this, Dee. I have White Birds growing in my garden that get easily 20ft. tall. They grow fast, if given warmth and lots of water, and in the size of pot that one was in, you'd need a lot bigger pot very soon or it would start having issues.
They should never sell White Birds as house plants, jmho. Unless you have a 3-story house with a glass roofed atrium, it's going to be too big in a hurry..
