I was all about Attachment Parenting, before I had my daughter (my first). She slept in our bed, and at about 4-5 months she just kicked and kicked, and we laid her down in a crib, and she fell right asleep. She was happier there! So I wasn't going to make her stay in our bed! Also, I couldn't breastfeed either of mine (with much help from lactation consultants, support groups and midwives I made it 6 weeks or so with each, I don't make milk properly though, and while I had the quantity I didn't have the quality, no hind milk, so my children rapidly lost weight). I was fine with the just about constant nursing, but it was a little difficult. But because they took to formula easily, and wouldn't go back to me at all once they had tasted formula, I ended up bottle feeding both of them - that again, messes with the whole philosophy. My son left our bed around age 2, though he still comes in early in the morning when he wakes up (about 6:00) to cuddle with me, and we lay down with him until he falls asleep. I want to be 'there' for them physically, emotionally, everything. My kids cuddle with me a LOT during the day! I wore them each, but it was different, my daughter hated it, my son did fine until about a year, then he struggled against it. So you do have to take into consideration personalities.
I know lots of babywise families too. THat wasn't going to work for me! I'm a big fan of Dr. Sears. Check his books out if you can, SO much knowledge, and so many different ideas to adapt to your situation! (NOT a book of how-tos or rules at all!!)
