When your toddler pretends their wooden block is a phone, they’re showing that they can manipulate information and that this pretending can be shared.
We think that’s quite impressive, but if you’re not convinced, here’s what your toddler is showing they know when they pass you that ‘phone’...
They can think about thinking
Pretending is a step towards metacognition (thinking about thinking), which is an important part of learning.
They can think about other people’s thinking too
They’re not only thinking differently about an object, but understanding that those around them can do the same.
They know the words you use can support their imagination
When your toddler hands you their ‘phone’, you will probably say something that shows you share their idea that this block really is a phone!
