Just a quick thought - when you say you are holding/rocking her....where are you? Are you standing in her room doing all that, pacing the floor or sitting comfy? The reason I ask is that if this is something your little one just does and all you can do is hold her.....at least make sure mummy is relaxed I've actually done this.....knowing that my little one will not go to sleep without a major protest, for my own sanity (through bubby's crying) I've made a cuppa, popped it near me so it's easy and safe to get but allowed my little one just to cry on me. I might pat or rub her back, whisper, sing etc....(knowing that it just isn't going to work but done it all the same) but most importantly, I did all that I could to keep my thoughts and brain at ease and relaxed - TV on quietly in the background or music playing.....for me that is (psst: didn't always work ) I just found it helped me get through sometimes......anyways, just a thought and a for you love
