You can let your child sit in the bouncer for as long as he or she is content. Your child can also sleep for short periods of time in the bouncer if he or she is comfortable doing so. We recommend that you use the lowest position or the middle position to give your child maximum sleeping comfort. However, small children should not sit or lay still in the same position for long periods of time. Therefore, we recommend that you pay attention to your child's needs and switch between using the bouncer and, for example, a baby carrier, your arms, a pram or a crib. You should always use the baby side with the safety harness fastened for small children who cannot sit unaided.
