Tummy-time companion:
Place a card in front of your baby during tummy time to encourage head-lifting and focus.
Side-lying view:
Prop a card beside your baby for gentle visual tracking practice.
Slow card change:
Hold a card 20–30 cm away and slowly move it side to side to support eye-movement coordination.
Crib/car seat display:
Attach a card nearby (within safe distance) so your baby can look at it during awake, supervised moments.
