That is a normal question for me at interviews. They want to know how many children their child will be with - some love the idea of lots of pretend siblings and others think their child won't get enough attention if there are too many. They also want to know the age mix - again they want to be sure that their child won't be the odd man out and programming will be geared to a level they are not at while others like the idea of their child being the only baby in care and assume the provider will be able to devote special attention to the baby.
