The start of the new school year means new friends and new experiences! It's big sister's first day of 3rd grade, but it will be a cinch for her to show little brother the ropes on his first day of kindergarten. She already knows where all the rooms are, who the teachers are, and where to go and when at their school! It's great to have a sibling to rely on when starting something new! PreK - Grade 1.
