I slow down my speech as well. As adults we are unaware of how fast we talk. In the prepared Montessori classroom environment everything is neat and orderly. The decor is warm and simple. There is a different learning style for every child.
Some children are just more physical than others.
It's using that characteristic in a way that will benefit the child. For children that need a lot of gross motor activity before they are able to sit down for a lesson or to work on a more refined activity there are activities in the classroom that the child can carry. Heavy basins of water or objects for transferring can help the child to develop upper and lower body strength. Some children need this before they are able to sit down with a work. Please speak with other toddler direcresses and get a lot of feedback before you come to any conclusions about your little one.
