@Laura I've been using the teething stuff, but was considering Calpol. I'll look at getting some nurofen because it helps with swelling. My LG is the same, worse when tired. Thank you mumma!
Usually when a tooth cuts it wouldn’t disrupt sleep for more than a few days per tooth unless you have many erupting at once. She could just be going through a development phase/ hitting milestones that are impacting sleep, sleep goes up and down constantly. Our little boy is nearly 2 and generally a good sleeper but we still hit random bumps in the road and not always clear what it is. I always just check are day naps still right for the age and are we being consistent with routine where possible - these things usually help things get back on track!
Hmm it sounds like it's possibly more teething, have you tried any nurofen or anything to try help ease the pain? My LG is 8.5months and is cutting her 2nd tooth now she can be fine and then randomly start crying however it seems to happen more when she's tired. I've used nurofen when it seems really sore after she comes out the bath, before her last bottle and it has helped her to be less fussy at bedtime on those occasions x
