Wanted to give some hope to others. At 11 months I think my daughter is finally sleeping through the night and we didn't have to sleep train. I think the biggest factors have been her moving to the one year old class at daycare and starting to walk. In the new class she's taking one long nap and maybe an afternoon cat nap. We transitioned her out of her sleep sack and just give a blanket and keep soft music playing at night. I am still breastfeeding so sleep training was really hard because she just wanted to comfort nurse all the time to go back to sleep! Just harin there may be hope for others if you don't want to CIO!
