It may not be the most attractive-looking gift in the world, but I promise you any woman in her third trimester will be happy to receive this Hidarling Maternity Support Belt (£12). Fastened tightly, it helps support the bump, reducing strain on the hips and groin, and it's surprisingly easy to conceal under clothing. If she walks much during the day, this will be invaluable as she inches closer to her due date.
