IMOGEN and Kate Little are among the thousands of prep pupils starting school this week.
The five-year-old twins, who will attend Sunbury Primary School on Friday, are looking forward to spending time in the playground and playing with toy trains.
Their mother Jo says they are both excited to be heading to school.
"We originally looked at holding them back another year, but in the end it was an easy decision."
Her other two children are in secondary college.
