I used to work in church nurseries and daycares, and one thing I have learned is that most children are naturally affectionate to those that they feel safest with and often even other adults when the parent(s) is/are near. When they feel safe and loved, they will reflect that back.
As a parent, I would say that this does not always mean that they will be respectful or obedient. That is an entirely different matter, but establishing love and security go a long way toward developing the desired respect. But, as far as love goes, don't hold back with your child and they will not hold back with you. Hugs and kisses and "I love you's" can not be given too much, especially when they are infants and toddlers. Also, time together snuggling while reading a book or watching television. Praise while making cookies or picking up toys and cleaning. Children crave affection from parents. Give and you shall receive.
