Each classroom was equipped with a two way mirror, I was able to fully see into the classroom but unable to completely hear everything that my toddler said unless she was very close to the mirror. I often would hear her saying “no” or “mine” when interacting with the other children. One thing that I noticed was when she wanted attention from one of the teachers she would go to them arms outstretched and say “up”. It reminded me of my niece who is around the same age, she would say “Aunt Jami I want uppies” and I would automatically understand what she wanted. According to the text Infants and Children Prenatal through middle Childhood children’s ability to learn and store language largely expands between the ages of 12-36 months. Receptive language is defined as what we hear and understand while expressive language is defined as what we say to others. As toddlers grow they become more aware of their surroundings and are able to understand much more than we think. Receptive language is essentially what the toddlers hear so even though they may not be able to repeat everything they may hear their receptive vocabulary has a lot more words stored than they are able to actually speak. The toddler that I observed displayed examples of both receptive and expressive language. When the teacher would address the group for example to tell them to make their way to the table for lunch I could tell that she was listening and taking in what she was hearing. When interacting with the other children she would often respond saying no or shaking her head that gave me the impression that the word no is used a lot by her parents and or care
