Although this might seem little counter-intuitive, solid headboards and sides are better than those with soft padding. This is because hard boards will not cause suffocation. Therefore, you won’t find items that come with a lot of padding. Moreover, you should avoid adding soft padding yourself. In fact, it is dangerous to put anything inside the cradle with the baby. Even stuffed toys can be dangerous. Also, babies are less likely to hit their head on the headboard. Baby has to be older than six months to be able to move the head by themselves.
