I'm probably not someone who'll try controlled crying when the time comes but am not judging those who do. I know it has a good success rate, it's just not for me.
I admit I got sucked in with the whole 'if the baby cries and no one comes it learns that mummy doesn't always come if you're upset' stuff. But as I was driving home the other day and my 3 month old wailed LITERALLY the entire way home, I wondered if that causes the same problems anti controller criers say leaving them in their cot does?
Or am I being a total bitch and everyone else stops every 5 minutes to soothe their child when they cry in the car?
