What happens when babies are left to cry it out?
The fact that this is so commonplace in my culture (USA) is frustrating and enrages me. As a parent, it is your evolutionary instinct to comfort a crying infant. They are quite literally helpless and look to caretakers for all their needs. There's a deep seated biological reason it feels bad to ignore it. The fact that it is so uncommon in other cultures should make this obvious. What are the odds that the rest of the world and entire history of humankind were mistaken the whole time, until some behaviorists came along and figured it all out in the last century? Talk about infants having "attachment issues" makes my blood boil. They are supposed to be attached to you. It is very much possible to co-sleep and then gradually transition them to their own bed. Yes, it is frustrating and will interfere with your sleep. This is one of the many sacrifices of parenthood.
