Can I just say, infant sleep training is not for the faint of heart. I’m probably taking longer with each stage because once he masters one part, I just want to sleep at night so I am hesitant to move on to the next stage. We’ve only been working on it for a week and the first stage is getting baby comfortable with sleeping with his arms outside the swaddle. I may be starting a bit too early, we will see. Most blogs and experts recommend sleep training not begin until after 4 months old.
