Apart from the obvious hygiene benefits, a second-hand mattress may well have been compressed by the previous baby’s weight and so will not provide the firm, supportive and comfy surface your baby needs at this time.Firm: Choose a mattress that feels firm rather than soft as your baby needs to be properly supported when asleep.Right Fit: Always check the fit. Assemble the cot first then measure the mattress. The gap between mattress and cot should be no more than 3 cm to prevent tiny arms and legs from getting trapped.Optimum Support: Look for a mattress that is at least 10 cm thick – anything thinner than this won’t provide enough support for baby’s head, neck and spine.
