When you are working with a special-needs baby/child, s(he) may be very loose (hypotonic) at the extremities, but the core of the body (craniosacral) can be very tight. I have seen this pattern at The Family Hope Center for 13 years.
I saw a CP toddler this morning who was very tight in the left pec/arm with a zero-second brain cycle. When CFT opened the shoulder/arm, the cycle immediately opened to 30 seconds. Many times at the end of CFT, the craniosacral fascial system balances out with less hypotonicity. It is all connected.
