If your dream about a day care center featured children who were old enough to walk, it is a good omen of happiness in family affairs and/or school, whichever concerns you most.
If the children at the day care center were babies, the meaning depends on how they behaved.
If they were happy or cute, good things are coming to you through the help of friends. However, if the babies were ugly or in any way displeasing to you, look out for treachery in someone you trust. Helpless or sick babies are generally a warning of difficulties ahead, so be cautious in your friendship and love affairs.
