potty training early?

My daughter has gone 3 days already(while at home without diaper on) with no accidents. When she is at daycare she always wear a diaper and goes in it but I'm not really pushing her into it just letting her be naked at home and she always tells me when she needs to go. Any other moms have any suggestions on getting them to not go if they aren't just naked(it seems that's the only time she'll tell me she needs to go and never goes anywhere but potty when she's naked)
