I have to admit, I'm not a typical parent. Many of you have already realized this.
I'm not sure what PT / OT / Therapists learn in school, but I'm not thinking this is included.
One strong ceiling hook at Pediatric Therapy center
One unstable swing
One deep pressure seeking 5 year old
One lighter weight and smaller (but OLDER) 7 year old
One very wisely placed safety mat
One very open and receptive therapist
One crazy, "let's see what my two kids can do with this challenge" Mom
STIR for 5 mins!!!!
RESULT: No children were injured!!! Yippee for Mom (would have been difficult to explain to Father, "Yes, sorry but I had Jessica swinging with Alexis on her lap on an unbalanced swing")
and BEST RESULT: Alexis and Jessica loved it! Best thing ever!!!
Warning: Not for the weak stomached or and antsy-pants'ed. Could induce heart attacks or gasps for air.
