Also, iwould like to add something
your posion should always be infront of the child (facing you)
always try to bring any attractive toy and moved from one to other direction
and bring his hand to midline to his mouth to hilb child to look to his hand and to improve his awarness to his body parts
then later approximate child hand to his knee then hips then his toes!! this will help him to imrove his eye contact and his podue discovering
