Hi Michelle --
Like Cheryl, I never had triplets -- just twins. Also, what worked for me were pillows pillows and when there was no room in the bed, MORE pillows. Also sitting in the glider in the nursery was helpful when my back was sore or when I was having heartburn problems. Couldn't sleep in there for long, but it was something!!!!
You're doing GREAT!!!!! Keep up the good work and I hope you can find ways to get some rest.....
All the best,
Ilene
