Sabire, I didn't choose to f'feed because it was easier, or gave me more time to spend with older dd (14 months when dd2 born), I just couldn't get b'feeding to work. I was determined to have more success with dd2, because the first 2 months of dd1's life was a nightmare of, infected nipples, thrush and a tongue tie, so I was trying to b'feed, expressing, and bottle feeding.
Unfortunately I found with dd2 that although my latch was apparantly fine (well according to the MW's, anyway), I still had agonising pain for the whole feed, and for some reason all the time I tried to express as well.I didn't find latching on easy, and had to keep re-latching to try and feed, this wasn't helped by dd1 screaming next to me the whole time I tried to get dd1 latched on, and trying to pull her sisters head off my nipples(ouch!at the memory).
My dh was working long hours from a few days after dd2 was born, and I think if he had been able to be around more whilst establishing b'feeding, it might have been different.
When I moved onto formula, obviously the time spent trying to latch dd2 on was not an issue, so yes feeding was quicker. But, with both my dd's, I have tried to f'feed in as close a way to b'feeding as possible, I don't like someone else to do it, I fed on demand, went skin to skin when possible, had dd2 in bed with us for night feeds. I certainly held dd2 as much as possible, and spent a lot of the time with dd2 in a sling.
My house is a tip pretty much all the time, just slightly more of a tip when dd's came along!
