Objective To explore the effect of family interactive reading on speech rehabilitation in children with language development delay（LDD） aged 1-6 years old. Methods A total of 85 LDD children aged 1-6 years old treated in our hospital from January 2020 to March 2021 were divided into the study group with 43 cases and the control group with 42 cases by the random number table method. The control group received conventional drug intervention and rehabilitation training

and the study group received family interactive reading on the basis of the control group. The efficacy and satisfaction of parents were evaluated after 3months of intervention. Gesell Developmental Scale（GDS） survey and serum growth hormone measurement was performed before and after 3 months of intervention. Results The total effective rate in the study group was 83.72%

which was higher than 61.90% in the control group（P<0.05）. After 3 months of intervention

development quotient（DQ） score of GDS scale in both groups significantly increased compared with those before intervention

and those in the study group were higher than those in the control group（P<0.05）.After 3 months of intervention

the scores and total scores of the parents of the children in the study group on the rehabilitation effect

professional level

service attitude and humanistic care were significantly higher than those in the control group（P<0.05）. Conclusion Family interactive reading is beneficial to the improvement of language and motor behavior in LDD children aged 1-6 years old with high parents’ satisfaction.
