Help Baby Emma's Helmet Expenses

Emma is my granddaughter . She is now 2 months old. She was born with craniosinostosis. Joints called cranial sutures, made of strong, fibrous tissue, hold the skull together. Normally, the sutures remain flexible, giving a baby's brain time to grow until the bones fuse at about age 2.
Unfortunately I noticed right away that Emma's head was long and narrow unlike a "normal" shaped baby's head. We saw a pediatric neurosurgeon who has recommended surgery. After surgery Emma will have to wear a helmet,which during her growth will need to be replaced a few times.The out of pocket expense is $385.00 for the first helmet. Since Emma has a 2 yr old sister and mom is out of work right now ,funds are very tight. My son ,Christopher, has been trying to work 2 jobs to keep up with expenses,which leaves him precious little time to spend with his babies.He has also had to take time from work (unpaid) to take Emma to her appointments and will be out of work all this week due to her surgery taking place. Emma 's  surgery is tomorrow 3/15/17. and her first helmet will be within a few days after that surgery. 
Obviously I ask for this help for my son and his family out of love. I think the amount I have asked for help with will help them with the helmet expenses as they occur. I could not express how much this help would mean to them.  Normally we, as Chris's parents, would pick up these expenses but my husband has been out of work for over 5 years so that makes it a little more difficult for us to pick up all the expenses. Any help you feel you can provide would be veryh much appreciated.
Thank you for taking time to read this
