I just recently had to start PT on our 3 month old. I thought it would be easy since he enjoys the beating on his back. He does not however, enjoy the therapy on his chest and sides. My question is does anyone here use percussors for the therapy. Before we went everyone told us they would give us "cups" to aid in his therapy, but they have not mentioned it. I planon asking tomorrow at his visit, but was curious if people use them anymore. Thanks!
