After breastfeeding one child, and bottle feeding another, my thoughts are that bottle is MUCH easier as long as you've got a fully involved partner.
Bf was easy in terms of me just shoving a nipple in her mouth with no prep etc. But it was all me (many babies, including mine, refused bottles). When she fed 10 times a night it was all me. When I was ill with D&V, it was still all me. I could only sleep for as long as she'd go between feeds, and it took over a year before I got 3 consecutive hours! My first full night sleep was when she was 2.
My ff baby fed less, and we shared the feeds. She slept 3 consecutive hours from the start, and my first full night sleep was at 3 days. I then got either (depending on how we were sharing it) either a guaranteed 5 hour block every night, or alternate nights of 7 full hours. I didn't do any bottle washing or sterilising, and my husband didnt so any bottle making up.
I also didn't get up in the night to make feeds as we made them for 24hrs, stored them in a fridge (cool bag overnight) and I picked up a microwave second hand for £5 which we had by the bed. Waking to feeding in approx 30 seconds!
BUT a large proportion of men dont muck in, they don't do night feeds, they leave the bottle admin the the woman, or the woman falls into thr trap of thinking the man must sleep because of work, irrespective of how tired she is.
So if you have a man who treats patenting equally, then bottle feeding can be much easier. If you have a lazy partner, then you may as well breast feed as you'll be doing it all anyway.
Ps: not all women can feed lying down and doze back. It killed my back.
Pps: mix feeding might be the easiest, but requires a flexible baby!
