A nurse is reinforcing teaching to the parents of a 6-year-old child who has fragile X-syndrome and is manifesting cognitive delays. Which of the following statements concerning coordination of care should the nurse reinforce?

“You should focus solely on cognitive development at home, as professional interventions are not effective for children with fragile X syndrome."

“Since your child has cognitive delays, you should avoid social activities that could overwhelm them and hinder their progress."

"It's important to work with a multidisciplinary team to address your child's cognitive delays and support their development.”

“Cognitive delays in children with fragile X syndrome typically resolve on their own, so there is no need for specialized educational plans or therapies."
