You have not mentioned your child's age, which is one of the most important details needed to assess development. Based on the information provided, responding less consistently to strangers than to parents is often normal, especially if your child otherwise communicates, understands instructions, maintains good eye contact, interacts socially, and is continuing to acquire new skills. Please share your child's current age and other developmental milestones (speech, social interaction, play skills, eye contact, etc.) so that a more meaningful assessment can be made.
