Bette, this all sounds great. Do prepare yourself for his face to be very swollen for quite some weeks. Listening to the Doppler blood flow is reassuring isn't it.
This is extensive surgery and sometimes it is 2 steps forward and 1 step backwards.
Hopefully you have had a good nights sleep and are ready to encourage and motivate Reggie as he gets up for the first time. All very positive.
Thinking of you both, Tammy
