Its amazing how kids can make these issues so much easier to handle. I just recently had my gallbladder taken out through laparoscopy, so I have four incisions on my abdomen. Every day my toddler son would "check my boo-boos." He'd touch them and say, "They're gettin' better!" And in the beginning I still had that yellow stuff all over me that they use for surgeries, and he'd say, "Not so yellow anymore."
Little things like that put a smile on my face and made the whole thing so much more bearable.
Best of luck with your surgery. I hope you have a quick recovery!
