This warming belt was developed to help your baby with pain and colic. The belt contains a small, removable heat pad filled with rapeseed and lavender. The rapeseed gives off a constant warmth and helps your baby to relieve tummy pain. The light scent of lavender helps your baby to calm down and fall asleep more easily. The strap keeps the heat pad snugly on your baby's tummy at all times. The strap is fastened with Velcro and the heat pad has a removable cushion and is filled with rapeseed, which can easily be heated in the microwave. The inner cushion should be removed and heated in the microwave at 700 watts for 45 seconds. Check the temperature. If it has not yet reached the desired temperature, the cushion should be heated for a further 15 seconds. Always check the temperature of the cushion before use.
