John Tee.. heard many good things about him but he's super bizi so if you dont't have questions for him, the appt is usually very chop chop.
which LC did you check with? just curious.
as for the tearing/pulling sensation from your c-section scar, I'd imagine its quite normal as you're making it expand as the baby grows. Scar tissue isn't as flexible as regular skin so you'll definitely feel the stretch. Trying lotioning it more often.
with regards to bfg while preggy. Frankly speaking, as long as you're allowed to make love, you can breastfeed. That's the general rule of thumb. So you dont't really need to see a gynae with that issue. And to be honest, most uninformed gynaes would ask you to wean (because of kiasu/kiasi reasons). again, I've bfd through two pregnancies and babies and me were fine.
The first gynae I told encouraged me to stop. I didn't. The 2nd gynae just smiled and said "that's good".
