The purpose of this study was to evaluate clear processes in the development of eye-hand-mouth coordination in infants from the pre-self feeding stage. We filmed 2 healthy female infants sucking objects (big and small wooden sticks, small plastic cubes, medium and large wooden cubes) with a digital video camera every 2 to 4 weeks from 2 to 11 months (child A) and from 4 to 11 months (child B).
The following activities were observed： 1) manner of reaching for objects，2) grasping，3) change in line of sight，4) manner of putting objects into the mouth, and 5) compensatory neck movement.
Our conclusions were：
1. Hand-mouth coordination seemed to develop before reaching movement, and to be induced visually from the age of 5 to 6 months.
Object sucking in the pre-self feeding stage starts before the initiation of ablactation and ends by late ablactation.
2. The 2 subjects grasped stick-type objects and put them in their mouths earlier than cube-type objects. lt appears that stick-type objects are easier for infants to manipulate than cube-type objects during the developmental process.
