The Cot Linen Saver lies over your baby's sheets, saving multiple linen changes when they vomit, dribble, or drool and in the case of younger babies, when their nappy leaks. When used correctly, it is safely secured around baby's mattress at four attachment points with elastic and velcro straps, helping prevent bub accidentally pulling it up over their face. It is easily removed and replaced without the need to completely remove the cot matress and underlying linen. Can also be washed, tumble dried and back on bub's bed before their next sleep! Some mums even recommend the use of the Linen Saver on their own bed whilst breastfeeding / feeding in bed..... as we all well know, or will soon discover, accidents can happen anywhere!! Measures 102cm x 50cm, fitting cot mattresses and can be used for toilet training later, especially if you have a cot that becomes a single bed.
