I have a bit of experience of both - was hoping to breastfeed but knew it might be more challenging (flat/inverted nipples). My DD initially was only latching on one side (the more prominent side), and after trying to pump, breastfeeding support etc etc she wasn't regaining her birth weight, and I was getting anxious and stressed, so we supplemented with bottles/formula. I absolutely hated bottles - so much faffing, so much less convenient, and just felt emotionally like I was failing. And pumping never worked for me. We eventually got back to exclusively breastfeeding at around 4 months (just using the 1 side). By the point I was wanting to get back on track, DD was gaining weight well. So I went on a breastfeeding mission to feed, feed, feed and it worked.
Looking back, I wish I had never started supplementing and just kept persevering for a bit longer, but I wasn't in the right state of mind after birth.
Found it so much easier exclusively breastfeeding as didn't need to worry about bottles. Particularly in the night - so much easier to cosleep and breastfeed. I don't mind that it was all on me (I actually really hated people asking if they could bottle feed my baby when we were combi feeding - the only other person I felt was appropriate to feed baby was my partner).
Also, I give zero cares about breastfeeding from 1 side only - yes I was a bit lopsided, but did it matter? No.
I got pregnant for second time when DD was 16 months. Supply pretty much entirely went by 16 weeks. We've carried on dry-nursing, but I've had awful aversions during pregnancy, and its the only time I've really not enjoyed breastfeeding. We've been slowly reducing and reducing. I've just started dropping the last feed before bed, and my DD is 2 years in a few weeks.
I'm 34 weeks pregnant and whilst I'm going to try to get breastfeeding established on both sides, I'm also not going to tie myself in knots over it.
