i had tubes tied at the same time as c-section. just ask your baby dr who doing the procedure and they will get you to sign form before procedure. they then ask you again after they have delivered your baby...
i was sore for 24 hours after delivery and couldnt get out of bed unassisted. but that is all a past memory now. i thought it would easier than going back in, falling pregnant accidently or just finding a babysitter for the boys if i had it done later.
we had tubes tied as we couldnt afford more childre3n and we were "highly fertile" (i.e. DH would walk past me naked and i would fall preggers!)
at the time it was best for our family but now our finances are awesome and we are doing ivf for #3!!!
but to answer you directly - the recovery time is about the same as just c-sect on its own..and i would recommend both at the same time. good luck honey!
