Linda Messbauer has recently been featured on the She Knows Parenting web site, in an article that details the creation and use of a Multi-Sensory Environment.
In the article, Linda states:
"A multi-sensory environment is not a plug and play toy," Messbauer emphasizes. "Look for a qualified person who has actually been through at least two to three days of training — at least 16 hours working and learning in an actual MSE room — and has worked with children in an MSE for at least one year for assistance and questions before you buy materials."
