Okay so I am at my wits end...

DD has such a hard time falling asleep recently.

Her first wake window is 2.5 hours then a 1.5 hour nap, second wake window is 2.5 hours then a 1.5 hour nap, 3rd wake window is 4.5 hours and in bed for the night by 7pm. Thats how its been for a while but now she fusses and fights me for 30 or so minutes during the day and before bed time we are up an extra hour and she doesnt go to sleep until 8pm because she fights me. shes almost 13 months old, the internet has all different bedtimes and total hours of sleep needed so I'm so confused... Should I be putting her to bed earlier? Like 6pm? I have tried keeping her awake longer during the day but she fights the naps even more...

Any advice would be awesome
