If a 10-month-old and a 12-month-old child are placed in the same room, what type of interaction can be expected?

At 10 months and 12 months of age, both children are typically in the phase of development characterized by solitary play. This means that each child is likely focused on their individual activities rather than interacting with one another. At this stage, toddlers may be interested in toys but may not yet demonstrate the ability to engage in cooperative or interactive play where sharing and joint activities occur.

It's important to understand that while they may be in the same room, the nature of their play is more about individual exploration. Children at these ages often observe each other, and might occasionally exchange glances or engage briefly; however, true interaction such as sharing toys or working together on activities is not common at this developmental stage. Social skills and the ability to engage in more interactive or cooperative play tend to develop as children grow older, usually around 2 to 3 years of age.
