I was unsure what to vote for because while we did use CC for DS, we didn’t for DD.

I also don’t think we were as strict as the official controlled crying technique, IYKWIM?

With DS it was pretty easy to tell what was I need something cries and just crying for the sake of crying. It also only took about 2 weeks for it to start working and he would fall asleep no worries. But we also started swaddling in that time as well, which is what I think had the most impact.

DD was completely different, she was crying non stop because of the pain, we had so much trouble feeding her, getting her to sleep, stay asleep, keep her feeds down. She ended up co sleeping for the first 6-9mths (not every night after 6mths), I also started using a sling for the first time because she was so uncomfortable laying down.

So I voted yes and had a little success, because I think it helped with DS but I think the swaddling was the major factor!
