I applied for my child's nursery place a year ago, to start this sept. I've spoken to the nursery a few times now and they won't tell me where my kid is on the waiting list. I'm starting to doubt they've put her on the list. They can't tell me how many places they're expecting to become vacant in September when kids leave the nursery to go to school. They are so vague about everything. How pushy should I be?
