While it may seem at time that your baby is just laying around not doing much...nothing could be further from the truth. Babies do a huge number of things internally, they are very intent human beings determined to overcome difficult circumstances such as blindness, deafness and immobility. At birth, a baby is born functionally blind, deaf, and immobile. Baby's bodies & brains are full of sensory and motor pathways that grow and develop through stimulation. Interacting with your child through verbal communication and eye contact really help with stimulation but even without your constant attention human instinct for self preservation is strong. Babies can self stimulate, by looking at their surroundings, listening intently to noises and by kicking and moving their arms & legs. While many of these movements may be involuntary they are inner connected to the sensory pathways that need to be strengthened.
