@jesussavedme2017 I don't think you're doing anything wrong! You're trying your best and you're giving it a lot of thought, energy, and effort. This shit is so hard, especially as the default parent. There's so much riding on us to get it right all the time.
I'm not sure if you're looking for help, so if you're not, please disregard the next part of my comment.
Some things that have really worked for us are lots of outdoor time. I read something a while ago (sorry, no source!) that babies will sleep best at night when they've been outside for at least 4 hours during the day. We definitely don't get 4 hours every day but I always make getting outside the goal.
Getting your baby outside (depending on where you are in the world, too!) specifically to see the low solar angle sunlight (around sunrise and sunset- and NOT just when the sun is at the horizon), is the optimal stimulus for setting their (and your!) circadian clock for daytime wakefulness, night time sleep, and overall mood. We personally do 10 minutes on clear, sunny days and 20 minutes on overcast days. If you do this for 1 week consistently with your daughter, I guarantee you'll notice a difference. It's honestly SO easy, free, and you'll also feel soooo much better.
This is a super unpopular opinion and I'll get downvoted for this, but we cut out all caffeine, including dark chocolate from my (EBF) diet. This won't be effective for everyone but it's really key for our family who is very sensitive to caffeine.
You might already be doing this, but tons of active play and new experiences at this age seems key to genuinely tiring them out. Lots of climbing, tunnels, thinking games like peekaboo and hide and seek. If my son doesn't have enough free play throughout the day, I find he wakes up more in the night.
Sending lots of good sleep vibes your way!
