Which type of play would the nurse suggest to the parents of a 9-month-old infant? Select all that apply.

A. Push-pull toy: Push-pull toys are more appropriate for toddlers who are walking, typically around 12–18 months. A 9-month-old may not have the motor skills to use such toys effectively. This type of play exceeds the developmental abilities of most infants at this age. B. Pat-a-cake: Interactive finger play like pat-a-cake encourages social interaction, fine motor coordination, and cognitive development. It is appropriate for a 9-month-old who is developing hand-eye coordination and enjoying cause-and-effect activities. C. Soft stuffed toy: Soft toys provide tactile stimulation, comfort, and safe exploration. Infants at this age explore objects through touch and mouthing, making soft toys developmentally suitable. They also support emotional attachment and sensory development. D. Large plastic ball: While large balls encourage gross motor play, rolling or chasing a ball requires more advanced motor skills than a 9-month-old typically possesses. This type of play is more appropriate for older infants or toddlers who are crawling or walking proficiently. E. Peekaboo: Peekaboo supports object permanence, social interaction, and cognitive development, all of which are emerging around 8–10 months. This game is highly appropriate for a 9-month-old and reinforces early learning and bonding with caregivers.
