I wanted to be sure and let you all know about an amazing continuing education course that's happening this spring (and which you can register for now at a discount until March 6). If someone asked me what has helped me the most in dealing with child/parent management at the library, then without a doubt I'd say this class called Child Development, Library Space, and Behavior: Set Up Your Library for Success.
Informally, it's known as Iron Fist on the blog Bryce Don't Play. She breaks down the class on this post and includes a link to the registration page (which I've linked to above). You can also read her thoughts on Iron Fist here, here, and here. Therefore, you can (like I did) learn the basic information about what is taught in this class, but WOWSA! the class really brought those lessons home and gave me greater confidence.
Please feel free to comment here or send me an email (firstname.lastname@example.org) if you have any questions about this course.
