Your question is relevant to what I've struggled with throughout my general surgery residency. While I don't "hate" gen surg, it is not, nor has it ever been my choice for a career. A means to an end (at one time it was PRS, now I'm looking at Breast Oncology), if you will.
As an intern, I spoke with our of our PRS residents whom I'd heard felt the same way about gen surg; when I inquired as to how she did it, she replied, "I put my head down and struggled through." I've done the same and while there are very few gen surg cases I look forward to doing (only if I really like the attending do I get interested in them basically), I have almost made it through (1 more year).
Of course, time in the lab is almost a guaranteed requirement for Peds Surg (and yes, there will be someone who will reply here stating they know someone who didn't require it. I even know someone from a community program without lab research who got a Peds Surg spot; then again, all of his ABSITE scores were 99%). Perhaps the time off from operating will be good for you and help you get through; perhaps it will make you dread going back even more. Peds Surg is a difficult fellowship match; there are other options which would involve operating on children should you not get a position after all your pain and suffering. Burn Trauma with a practice at a Shiner's Burn Center or Trauma/Crit Care at a Chidren's hospital are options for example.
You've been given some great suggestions - if they are of interest to you, the other surgical specialties like Ortho, ENT are great options for working with children, at least throughout your residency and beyond (you will have Peds Surg rotations as a Gen Surg resident as well). Almost all of the Surgical specialties can offer a great career in peds - neurosurg, plastics, urology, etc. Peds gastro doesn't do as many procedures as their adult counterparts but may also be of interest to you. All of these are obviously competitive matches as well but may be a better option if you truly "hate" gen surg.
Obviously no one can tell you whether or not this is a road you want to take. I can tell you to spend 5+ years doing something you "hate" would be extremely hard; its hard enough even if you can only just tolerate it (heck, its hard for anyone, even those who enjoy it).
Best of luck to you.
