At wits end with sleep

Every type of sleep is a problem. Napping. Bedtime. I am so exhausted I don’t have time for 1-2 hrs of fighting bedtime (and this is with rocking or me being next to her so she can sleep). We do everything before bed- running around releasing all energy, shower, books. I don’t know what to do anymore. We follow wakes windows and even pass the sleeping window. Any recommendations?
