Understand that nannies and au pairs are different so if people could answer the poll only if they've used a childminder or nursery please, but SFE seem to think "all childcare providers" accept payment in arrears because "how do you know what hours you'll need every week until you've had them?". Every childcare setting and provider I've used has stipulated you must book for a whole or half day anyway and pay in advance, am I just out of touch?
