Breastfeeding is very hard in the beginning, maybe until 6-8 weeks. After that it's easier but still hard to get a break as unless you're able to pump (it took me about an hour to produce a tiny amount and it was very uncomfortable, both physically and mentally so I gave up on it), you're stuck with being back for baby feeding times.
I had the whole overwhelming love for baby as soon as he was born (not everyone does, perfectly normal either way) so I can't say if breastfeeding made any difference to bonding.
I think where it comes into its own is just how easy it becomes to go anywhere. I was kind of resentful when DS started being hungry for solid food and I had to pack food for car journeys and so on, or even if I was just off to the shops for a few hours or something, because I was so used to just bringing nappies and wipes and a change of clothes. And it was free, which was handy.
It was so easy in the end I kept feeding him till he was over three. At that stage you're not tied down at all, but it's a handy comfort thing. Even before that I remember when he was starting on solids I didn't worry much about nutrients as such as I knew he was getting good stuff from breast milk.
The first few weeks were horrendous though. I've got no idea if bottle feeding would have been easier in those weeks, probably a bit, if only for the break, but I'd imagine the sterilising and all that might have been quite hard work too, and at least I didn't have to bother with any of that (after giving up on the breast pump carry on).
The ideal thing would be if somebody else would take baby any time you're not feeding, so that you can wash, eat and sleep. That person should be responsible for cooking, cleaning and doing laundry too.
I think it's the pressure to get other stuff done makes it so much harder to not feel frustrated with the cluster feeding on the beginning.
