Why ratios are the backbone of a safe mobile creche

Adult-to-child ratios are sometimes treated as a box-ticking exercise, something to note down in a file and forget about until inspection time. In a mobile creche, though, they are the single most useful planning tool you have. A fixed nursery knows its rooms, its numbers and its routines weeks in advance. You are setting up in a hotel function suite, a village hall or a marquee, with children you have never met, parents coming and going, and a team that may not have worked together before.

Get the ratios right and everything else becomes easier: nappy changes happen without leaving the room short, one unsettled toddler does not pull a whole age group off course, and staff finish a session feeling capable rather than frazzled. Get them wrong and you are supervising by hope.

The core ratios for early years childcare in Scotland

Scotland's early years sector works to broadly consistent expectations, and mobile creche providers should plan to meet or exceed them. The commonly applied minimums are:

• Under 2 years: one adult to three children
• Age 2 up to 3 years: one adult to five children
• Age 3 and over: one adult to eight children
• Older children in out-of-school or holiday care: often one adult to ten, but confirm current expectations with the Care Inspectorate for your type of service

Alongside the numbers, services caring for children under three should have at least one member of staff with a relevant early years qualification on duty. If you care for children under 16 for more than two hours a day on more than six days a year, registration as a daycare of children service is likely to apply — worth checking early in your planning, as the rules shape everything from staffing to paperwork.

Who actually counts towards your ratio

This is where well-meaning teams come unstuck. Only adults who are directly responsible for the children in front of them count towards the ratio.

• Count: staff on the floor, actively supervising and engaging with children
• Count, but only while in the room: managers or senior staff who step in to cover — they cannot be counted while dealing with enquiries, admin or a phone call
• Do not count: volunteers, students on placement, kitchen and cleaning staff, entertainers or photographers
• Do not count: anyone on a break, even if they are sitting in the corner with a coffee

As a rule of thumb, a nappy change, a feeding session, a first-aid incident or a lengthy handover to a parent takes one adult out of the count for anything from ten minutes to half an hour. Build that reality into your staffing rather than assuming it will work itself out.

Planning for mixed ages and real pinch points

Mixed-age bookings are normal at weddings, conferences and family events, and the ratio should always be set by the youngest child in the group, not the average. Ten three-year-olds and two babies are not a twelve-child group at one to eight; they are a mixed group needing separate thinking.

Group children into zones by age and stage, with staff assigned to a zone rather than drifting between them. Pinch points to plan around include arrival and collection, mealtimes, sleep times and the last half hour of any session when parents gather. A child with additional support needs may require one-to-one support, agreed in advance with the family and, where relevant, the local authority. Never quietly absorb that need into your standard numbers.

A worked example and a rota that holds up

Picture a wedding creche for fifteen children: three under two, five aged two to three, and seven aged three to five. Under-twos need one adult; the two-to-threes need one; the older group needs one. That is three staff as an absolute minimum.

In practice, schedule four. The fourth adult covers breaks, nappy changes, a distressed child and the busy collection period, and gives you a fighting chance if a child is collected late. For longer events, stagger shifts so nobody is on the floor for more than a few hours without a proper break, and have one additional person on call locally in case of sickness or an unexpected rise in numbers.

Records, registration and staying inspection-ready

Good ratio management is also good evidence. Keep a simple record of children present, their ages, staff on duty and any planned one-to-one support, updated as the session runs. If numbers change mid-session — a late arrival, an early collection, a child moved to a different zone — note it.

Alongside this, hold current staff qualification certificates, PVG scheme records, attendance registers, accident and incident logs, and a venue risk assessment. Inspectors and parents alike want to see that your numbers were right at every point in the session, not just at the start. Build the habit of a two-minute ratio check before doors open, at the midpoint, and again before collection begins. It is a small routine that protects children, staff and your reputation as a provider worth booking.
