One of Jessica’s favourite books at the moment is the “Thomas Weather” book. This is a really simple book about Thomas The Tank Engine, his friends and various weather conditions. When we got to the snow page the other day Jessica turned to me and said, “We play in the snow… yesterday!”. She was clearly referring to when it snowed a few months ago. So she’s not quite cracked exact time-spans yet but the idea of “the past” is there. I wonder if this is when lasting memories start to form — when individual events can be distinguished in time?
