From eight a.m. to ten a.m. every Sunday morning for a month, I spent my time observing a classroom at my church that accommodated children aged one to two years. In the class I was in, there were children who had just celebrated their first birthday and others who were about to turn two. The difference between the kids who were just able to squeeze into class and those who were on the verge of being able to move into the "big" class was huge most of the time. Observing this group of toddlers, I was able to see the differences in attachment, language, temperament, gender and was it going to be screaming, kicking and crying when the child was ripped from his parents arms or the exact opposite, the toddler was he is going to walk into the room and never come back because their parents left them alone. Being an observer in an environment where toddlers were separated from their parents was a great way to see differences in attachment. The attachment that forms in toddlers typically peaks between fourteen and eighteen months, which was the main age group I observed on Sunday morning (Sigelman & Rider, 2012, p. 457). I was surprised to find that most of the toddlers dropped off showed no signs of serious distress. A few toddlers were harder to separate from their parents and cried for a while, but seemed to calm down when playing with the other toddlers. Toddlers who showed the most distress seemed more excited to see their parents after the services were over. It seems like these toddlers have a secure attachment. Sigelman and Rider (2012) describe secure attachment as a toddler who "may be upset by separation but warmly welcomes mother and is in the middle of a paper......atty, gentle and talkative in a softer tone, if talking to boys they would use words such as tough, handsome and speak in a more masculine voice. Although the toddler won't remember it, it could affect how he views himself as he grows up. .From differences in play, temperament and differential treatment to attachment and language, everyone develops at a different speed. As I observed these toddlers, I saw the proven medians of development as well as the outliers. parents and realized how this could affect attachment as they grew up. Every part of the development is important and it was very interesting and exciting to be able to see this first hand.
