Doesn't have to be a sewn in label, just a name in or on everything. A laundry marker would do. Put on jumpers, shirts, p.e , bags, shoes....especially p.e pumps! Please put a name in coats too!! And on bags and water bottles- those sticky labels you can buy are ideal for this.
I work in a school and this week I have spent so much time trying to find items of clothing. At this time of year, the lost property cupboard is overflowing. It is heartbreaking seeing lovely coats, smart trainers and hundreds of identical jumpers all with no name on!!!!
