You can let your child sit in the BABYBJÖRN Babysitter Balance for as long as he or she is content. It’s even fine for your child to sleep in the babysitter for short periods if he/she enjoys that. However, small children should not sit or lie in the same position for extended periods. That’s why we recommend that you pay close attention to your child’s needs and switch between the babysitter and, for example, a baby carrier, baby carriage or bed.
