Hi L.! My "perfect sleeper" also did this at about 8 months and I had to let him cry it out, even though I had NEVER done it before up until that point. He cried 20 mins the first night, 15 mins the second, 10 mins the third, and now he's back to being the perfect sleeper again! :) If both you and your husband are home, and he can take the crying better than you can, get yourself out for a walk, or water your flowers, or any other activity that gets you outside if you can. I couldn't take the crying but my husband could, so as soon as I laid my little man down I grabbed the leashes for our dogs and I took them for a 20 minute walk. Problem solved for all of us! It made me feel bad too at first, but I just chalked it up to a long list of things I will probably feel guilty for in the future! :) Good luck!
