My DSIL and I had our babies within 4 weeks of each other, I EBF she FF.
I did have sore cracked nipples which we quickly resolved when I found MN and they told me about Lansinoh which fixed that within a day or two.
ds was sleeping through the night (11pm - 6am) from 8 weeks, dn didnt sleep through until 6 months - every baby is different and ff or bf wont define this for you
by the time bf was really established around 8 weeks, when visiting DSIL, by the time she had prepared dn's bottle, fed, then winded I'd finished ages ago. Feeds once established could take just 5-10 mins and ds rarely needed winding. There was no looking at the bottle and worrying about the fact she had only drank x ounces when she should have drunk Y and will I now need more bottles for later.
Our kids are teenagers now, but back when they were babies bottles were prepared in advance, but DSIL struggled to know how many to prepare as she would try to feed one and dn would refuse and would need to prepare more during the night. With bf it is always ready.
My dh was very involved with our ds, he put him down to sleep, he bathed him most nights, changed a lot of nappies/clothes, took him for walks around the park while I grabbed a nap etc etc etc. Feeding is only a tiny bit in the first 6 months before weaning.
Don't agree with mentally and physically draining anymore than having a baby and ff would be. bf releases feel good hormones, your body is designed to bf so as long as you take care of yourself and all goes well it shouldn't be any more draining.
DSIL didn't bf just because she couldn't get her head around it and it just didn't feel right, I did not judge her in anyway, her body her choice. She is happy about her choice and I mine. If you just dont want to bf your choice, but if its for the reasons you stated above they are worst case scenarios for everything and no consideration for benefits if bf actually works for you.
