A 10-month-old infant demonstrates object permanence by actively searching for a toy hidden under a blanket. Which nursing action best supports the infant's cognitive development at this stage?

Limit the infant's exposure to new toys to avoid overstimulation and confusion,

Encourage parents to play peek-a-boo and other interactive games that reinforce object permanence.

Discourage exploratory behaviors such as putting objects in the mouth to prevent choking hazards.

Focus solely on physical milestones such as crawling and walking, as cognitive development is less critical at this age.
