Bridee, I hear you. For 2 weeks now, we've been trying a new sleep routine which is quite good. She did have her dummy at the start but I just didn't give it to her anymore one day and she protested but it took about 2 days for her to live without it. Now she's sick and the sleep routine has gone out the door. She is all over the place! I know exactly what sleep deprivation feels like. It's horrible isn't it?! My DD is 6 months old. I am trying everything from not giving her solids after a certain time to giving her Infants Friend, wondering whether she is hot/cold, giving her teething drops, everything! Nothing is working, I'm thinking it may be developmental. I have heard they go through stages of sleeping/not sleeping.
