as far as i know it is a building a place that you can visit alone or with your toddler so they can use the premium contents but i do not think you can use the building for a daycare career, you will have to buy yourselve all the toddler stuff and do it in your lot or you could change the Daycare building into a regular lot where your sim can live, sorry i am just awake and do not have my glasses on
hope this could help a little
