15 month old sleep regression vs teething

Kiara

My daughter has only slept through the night twice, ever. It seems like when she gets close to doing it again she is either teething or at a stage where she might be having a sleep regression. Right now shes getting 3 to 4 teeth in and waking up 3 to.4 times a night😳. We do ibuprofen on really bad nights. Shes also.going through some separation anxiety, which I hear is normal. Will.she ever sleep through the night? I heard theres a 18 month sleep regression and a 2year old one too. Will we ever get to sleep lol. We have whole nighttime routine and shes down to one nap a day now. Any insight or suggestions on how to help her sleep better at night?
