Mom, have you ever used a crib block?
It's better to hold it and prevent the baby from rolling or falling off the bed.
In summer, you can also put mosquito nets. I buy mesh fabric guardrail, which is characterized by strong and soft, do not worry about knocking bump into the baby, the inadequacies are not as good as solid wood railings, but also easy to dirty, need regular cleaning.
Good or great protection?. I think it's very practical! If I don't have a bed, my baby will fall N times! Every time I wake up, I'm close to the implantation site.
