How long have you let your LO cry alone. I'm not passing judgement on anyone...I'm just curious.
I'd have to say maybe 10 minutes on our way home one time. I pulled over, but he wouldn't calm down so I had to drive with him crying. It was so upsetting for both of us.

Re: s/o ferberizing
I'm the same way when I'm driving the longest I have let him cry in the car was 20 minutes on our way down to DH's work for lunch. It was raining cats and dogs and I just could not pull off the freeway, by the time we got to dh's work I was crying too!
I'm not passing judgement on those who ferberize, but I just couldn't do it. I know a lot of people that it really worked for.
I let her cry if we are in the car and driving. Usually she just starts crying when we stop (at a red light) and stops crying when we go again.
We drove to a place 45 minutes away, and she cried in the first 10 mintues, so I pulled over and fed her.
Otherwise (at home), I'll let her fuss until she actually cries (I don't usually go in if it's grunting and stuff). When she cries, I go in, try to soothe her, put her paci in, stroke her forehead to her nose and when she calms down, I walk out. I repeat this for about up to 5 times (so she, if crying the whole time interspaced with me calming her down lasts about 20 minutes), but if she's really crying and not calming down at all I dont usually let it continue after about 5 minutes.
I don't really count time in the car as "letting them cry" unless you are driving somewhere frivolous like the mall, maybe. If its a trip you have to make, and they happen to cry in the car.. its kind of out of your control. Ya know?
We don't let her cry. I can't handle it. Lucky for us, she is a champion sleeper so we haven't had to worry about sleep training.. I seriously don't know what we would do if things were different.
I do not knock the ferber method though, I have known many people with wonderful success stories and whose children are wonderfully happy kids. I just can't do it. I'm a big wimp. I won't deny it.

To be honest, about an hour, but like other posters said, if you're driving and you can't do anything about it (like on a major freeway and stopping on the side would put your lives in danger).
With tonight's Ferberizing, he's calming down every 10 mins or so, not crying continuously. He even self-soothed for a while after 1hour of starting, but alas, 2 hours later, we're still suffering with a fussy infant. When he starts crying to the point of coughing, that's when we pick him up and soothe him again.
I don't consider crying in the car to be 'crying alone'. She knows I'm there and soothing her. It's totally different than putting them in a room, closing the door, and trying to ignore their cries, IMO.
In saying that, we've had two car meltdowns. I pulled over and fed her for one of them, and the other was two minutes from our house, so I just sang to her until we got home. Besides the car, I never let her cry for more than a few seconds...I can't take it!
those who posted about lo's crying in the car... have you tried white noise (am/static station)? when ds isn't hungry, white noise works every time.
we don't ever "let" ds cry intentionally, at most he's cried 10-15 minutes when i was too sick to pick him up when he was a lot younger (medical issues).
