Hi Stacks! Congrats again, and lovely to see you in here!
I had a planned section, and I was very lucky that the recovery went super smoothly. I'm a HUGE wuss when it comes to pain, so I took the max allowed dosage of both painkillers, until over a week after my cs, despite not really being in proper pain at any point. I'm certain I took the meds for longer than I actually needed them, I was just too afraid to miss a dose and find out how it felt unmedicated! It was a really short time, in retrospect, from cs to being pain-free whilst lying in bed without meds, I probably tried it for the first time around day 10 and it was fine.
As for giving one side a break from bfing - every baby is different and you have to see what you can get away with works for your LO. I had AWFUL engorgement at the beginning, it lasted from day 2 through to day 12 - a truly ridiculously unlucky length of time. Due to my anime-style rock hard balloon boobs, poor DD couldn't get a good latch and although she was a really good feeder my nipples became super sore very early on. At the one week mark one nipple in particular was so sore I was sobbing every time DD latched on, and I basically decided that I'd rather give up bfing than carry on with the pain. As a last ditch attempt to make it through the seemingly never-ending engorgement period I decided to give the extra-sore nipple 24 hours off duty. I fed DD as normal on the the other side, and then expressed from the sorest side and gave DD a bottle with the ebm. So DD alternated boob and bottle for 24 hours at 1 week old.
It is definitely NOT RECOMMENDED by bfing experts to introduce a bottle so early when you want to ebf, in case of nipple confusion. However I was at a point where if I hadn't been able to let my nipple heal I would have just moved to ff anyway, so I decided to take the risk. I was very lucky that DD took it all in her stride, she accepted the bottle without protest, and still continued to bf with no problems. After 24 hours off my nipple felt soooooooo much better and I was able to continue bfing on that side, my supply was unaffected (my problem was always over-supply). I ebf DD for 5 months, and only gave up bfing after 6 months, and throughout that time she had 1 or 2 bottles of ebm every day, whenever we were out in public.
The point of my stupidly long-winded story is that not every baby gets nipple confusion, and sometimes giving your boobs a break can be beneficial for bfing in the long term. Obviously I'm sure the bf experts are right, and perhaps lots of babies do get confused, but if it's a choice between giving up bfing altogether or having a break, I'd say it's worth a try!
