I'm so excited that after 17 weeks of waking every 1.5 to 2 hours to rock my baby back to sleep every night, my baby finally learned to self soothe and slept for 8 hours last night!! We used the Ferber method with the Merlin suit for 3 nights and by the 4th night he fell asleep on his own without crying!! I was so scared it was only a fluke but we had 3 nights of him sleeping 6-8 hours. Yayyyyyyy!!!
