Medical Bills and expenses

My son Nathan was born with Cerebral palsy and other special needs. He was recently suggested to use a  therapeutic tricycle in his inpatient therapy sessions which he loved and as his mother it brought me so much joy to watch him ride it. It will give him the freedom that will help him develop better mobility. The insurance unfortunately will not cover this but his therapist believes it will greatly benefit him physically and mentally. I want so badly to provide this for him. Please give or share. Every little bit counts and will be a blessing. Thank you
