Started with the ferber method last night. Son is 19 months old and in my room. Great. He fell asleep in 25 mins. That was a nice surprise and unexpected. Slept for an hour then woke up. Then proceeded to wake up every hour. I ended up bringing him in bed with me at 3:30 because I thought I was going to vomit due to being so tired. He doesn't usually wake up more than once when co sleeping. I am exhausted now. Can anyone help?
