The vision of a newborn baby is not yet as strong as those of an adult.You might be considering giving him or her toys such as crib mobiles that feature bright colors. Make sure, however, that these toys are positioned at least 6 inches from their face so that they can see it. You can also try letting your baby play with the mirror. Do not leave your baby unattended though as the mirror could break and cause injury.Once the tendency of the baby grows to grab the things which are within their reach, they are most likely to put things into their mouth. So in this case, your best move would be to get toys that are chewable.
