I'm a dad of four lovely children, I may not have first hand experience of breast feeding (I'd be a millionaire if I had) but I witnessed the bond between mother and baby for a long time. There is no better way to feed your baby but occasionally it can become a little complex.
One of our children used to use mum (yup I'm from London) as the only method of sleeping. So I would have to tip toe him back into his cot when he'd finish feeding only to hear him wriggling around and crying for the 47th feed in a night. It can become a vicious cycle because a tired mum and dad want to get back to the little amount of sleep you get and it's hard to break.
I wrote in more depth about this http://parentplaygroup.com/2014/07/09/sleep-training-the-boss/ and luckily we found a way out eventually. It might not work for all but it did for us.
