Then the baby sleeps gets longer and you can have 6-8h of sleep.
New fathers: Hold tight, after 3-4 months it gets way easier.
On the downside, breast feeding ad libitum basically meant my wife's full time job was to breast feed, we went on a date after our kid was a few months old and we had to cut it short because she was sore and it was feeding time. She estimates she spent 40+ hours a week breastfeeding. She played a lot of video games with our daughter latched on, since it could be pretty boring.
Like any parents, we had a few "hell nights" when she was sick or teething, but in general human infants are significantly happier (and much quieter!) sleeping next to their mother, and unless a mother is either drunk or under the influence of some other substance, you're not going to crush your baby. I slept significantly more soundly and slept in a different bed. Putting your kid in a crib in a different room is a very weird, Victorian thing to do.
I understand the attachment, but at some point you have to let go and life is full of risks (and interesting things).
Though I doubt my reasoning will assuage any parental fears :-)
Yeah how many teenagers do you parent? :)
