Registration for story-time sessions for 2-year-olds at the Acton Memorial Library next month and in February begins Monday. The program offers 30 minutes of stories, songs, finger plays, and other activities selected to engage toddlers. Children must be at least 2 by the first meeting, and a maximum of 22 children can be enrolled in each session, with preference given to Acton residents. Nonresidents are placed on a waiting list. Families can register in the children’s room of the library or by calling 978-929-6655.
