National standard for children's bed guardrail
So the proper barrier is right. The crib fence with a height of 50 cm is appropriate. If the mattress is too low, when the child can grasp the fence when standing, always dangerous climb over the fence fall down. If it is too high, parents hold up or down the baby is very inconvenient. So you can choose a crib with a movable door or a fence that can be lowered as a whole, so you don't have to bend your waist to hold the baby while you're carrying the baby or changing your baby, and it won't cause backache
