something fun to try with your baby is to prop him up in a sitting position in the corner of a sofa or big soft chair, kneel in front of him, look into his eyes and say something..."hello ..."
then wait until they make a vocal noise
when they finish say something else "oh really"
then wait till they make a vocal noise
when they finish say something else "wow" or "i know"
continue this for about five minutes at least once a day, it really helps them develop the rules of holding a conversation, taking turns and language skills needed. it really works, i tried and tested it and the child was talking properly well before her peers.

children who do not crawl have more difficulty with balance and co-ordination than those who do, so don't be too impatient for him to learn to walk.

try laying your son on his back, take his right hand and guide it to his left foot, then do the same with his left hand and right foot, then his right hand to left shoulder and left hand to right shoulder,... these actions help build the bridges that link the two halves of the brain to allow signals cross... great for babies and children up to age 7 to do regularly,
