My little guy has been an amazing sleeper from the beginning. Around 4 months he started taking 12 minute naps so I started following the 2 hours up, 2 hours down schedule. It worked perfectly until now. He is 6 months old and has recently gone back to 2 30 minute naps per day. I have tried everything. I have no problem with crying it out but it doesn't work for him. He will literally just lay in bed and cry for 2+ hours. I even tried CIO with 5 minute and 15 minute checks. I am starting to lose my mind... any suggestions?
