Yup it sounds exactly like my DD1!!!! She does the same thing when she is teething, Its definitely exhausting (I was up every 2 hours with her & was beside myself at 2am this morning)!!!! Have you tried Bonjela?? Also Panadol or nurofen help too, I also have a stack of teething rings in my freezer & she loves chomping on them (I keep a heap of them because when her teething is bad as soon as they start to warm up she throws them on the floor lol) I dont know how much truth is in this but I was told that she plays up when I lie her flat because teething can make their ears sore too & when they lie down it puts pressure on their ears!?!?! When DD1 is really bad I have resorted to putting her in a 1st years portable bed thingy in my bed next to me, its the only way I get sleep, I was also told too that having her dummy at night helps & it does seem to, But take heart, it only lasts a couple of days at a time, Hope this helps a little bit (if it makes sense lol, Im massively sleep deprived atm) & let me know how you get on!!!
