Every situation is different, so do what feels right to you and your foster son.....As for us, we started fostering our fosterson right before he turned 3. The first month or two he called us by our names, then he started calling me "mom"....a few weeks later he started calling my husband "dad"....this has been going on for almost a year. He now calls his birthparents by there names (I think this came from hearing the social workers call them that -- he has not seen his birthparents in over 6 months).

Good luck!
