Anyone have luck with this? Some nights go better than others, but our son just cries so hard some nights...! It breaks my heart. My husband says we need to stick to the method so he doesn't expect to be picked up all the time when he cries. Does anyone else have another suggestion in what to try? Or would you recommend sticking to his method? Some nights it works, some nights I feel like it doesn't. It also doesn't help that he is teething...
