It's been a GREAT few days!  Lincoln graduated from Day Rehab on Wednesday, they held a ceremony, all the therapists said great things about Lincoln and all the progress he has made.  Then Lincoln got to make a speech, thanking the staff and giving encouragement to the other kids.  It was really special.
Yesterday, we had our weekly clinic appointment, his numbers look good.  Then he went to school!  This was the first time he has been back to a regular school day since his surgery.  He has been out for 2 months.  It went really well; he was excited to see all his friends and all the staff.  He seemed to really enjoy doing something "normal."  It has just felt great to see him happy and doing all the things he did before December.  He is such an amazing kid.  
We are on course to have his next chemo cycle on 2/11, following an MRI.  So will keep you updated!
