Safety: The suspension height of a mobile above a baby bed must be adapted to the growing baby so it can not reach it and get entangled.
Field of vision: Newborns initially have a limited field of vision. They only see somewhat sharp at a width of up to 30 centimeters. Therefore, a mobile should initially hang at about this distance. The better your baby learns to lift his head and arms, the higher up the mobile will have to be.
Colors: Babies prefer bold and contrasting. Muted tones or pastel colors are more difficult to recognize.
Less is more: A wild mix of colors and shapes is not necessary. More than a handful of hanging elements of a mobile might overwhelm the baby. Also, the even rotation or the quiet rocking of a gently blown mobile fascinates them much more than a vigorously scuffed and hecticly dancing mobile.
Best spots: Wherever you would like to distract or calm a baby is a good place for a mobile. Such places are mostly over the cot or the crib, at the changing table and above the dining table. It's no coincidence that virtually every pediatrician has at least one mobile at their office.
Eyes and ears: Not all babies can use the mobile as a sleeping aid, some rather feel stimulated. However, the mobile can stll be nicely supported by sounds, a lullaby, a music box or white noise.
