Holds head up steadily in line with body for a few minutes (1 to 2 months)        

When on the Stomach (Typical 2-Month-Old)
Turns head to each side resting on the ear        
Lifts head for approximately 5 seconds (1 to 2 months)        
Lifts head briefly to a 45-degree angle while leaning on the upper chest & bending hips        
Lifts head in slight rotation, in the middle (midline), and/or with bobbing        
Uses vision along with head control        
Brings head/mouth to hand for calming        
Begins pushing body upward with arms        

When Turning Head & Body to Each Side (Typical-2-Month-Old)
Turns body with full head turn to side when lying on back (log roll)        
Turns from side to back from each side (1 to 2 months)        

When on the Stomach (Typical 3-Month-Old)
Rests arms symmetrically around the head        
Lifts the head in the middle (midline) at 45- to 90- degree angles without bobbing        
Shifts body weight from side-to-side as head moves to left or right (may roll to the side if body weight is adequately transferred)        
Visually tracks an object horizontally across 180 degrees while looking upward        
Props & bears weight on the forearms with elbows in line with or in front of the shoulders (crucial for shoulder development)        
Lifts the chest & lower the hips        
May make finger scratching movements or swimming motion with body & legs when seeing a toy        
Lowers head & shoulders when raising the hips (weight is shifted forward, minimal kicking occurs)        

When on the Back (Typical-2-Month-Old)
Begins gaining control over moro/startle reflex        
Turns head to each side & lifts chin        
May assume fencing posture with head turning (arm reaching outward on face side, elbow bent on skull side – asymmetric tonic neck reflex/response)        
May swipe at toys on the side where head is turned        
May briefly hold an object placed in the hand but not attend to it        
Seldom has head in the middle (midline)        
May visually follow a preferred object from midline to each side & from each side to midline while beginning to use binocular vision        
Head control & vision work together        
Moves arms vigorously (1 to 2 months)        
May rest legs in a several positions (e.g., frog-legged position)        
Uses movement variations when kicking        

When on the Back (Typical 3-Month-Old)
Moro/Startle reflex begins to disappear (become integrated by the brain) between 3 & 6 months        
Has head close to or in midline (middle of body), & begins to tuck chin toward chest & look downward        
Rotates head from side-to-side while lengthening back of neck (may turn body onto side)        
Looks at a toy in midline with increasing attention, & may swipe at it        
Visually follows a toy/face horizontally from side-to-side        
Typically has hands open with wrists & fingers spread        
Shows increase in hands & eyes working together (eye-hand coordination)        
Demonstrates increase in moving just enough for an activity (grading) & moving one body part separate from another (dissociation)        
Brings hands to the body in an increasingly coordinated manner, & begins to gain control over palmer grasp reflex/response        
Uses hands with increasing intention to explore mouth, body, clothing, & care-providers (body awareness & touch/tactile experience)        
Often has feet together for body awareness/touch experience (frog-legged position)        
Stretches hip, leg, knee, & ankle muscles when moving legs
