Hi there! Ill give you our experience with this at that age, which was only just a couple of months ago....
Hena can vouch for me, she helped me the whole time! And other moms on here too!
Our son went through a never ending 3 month long crazy sleep thing at that age. I wanted to drop his nap every single day, and we even did for 4 straight days! He wasn't ready. Or maybe I just wasn't. We didn't deal with EW but we had short naps, and short nights, and taking ages and ages to fall asleep at BT. We also had nws too. He was night potty training then too which contributed to the nws.
Our son is also on the lower end of sleep needs. So, in the end, and still now, 2-3 months after the craziness, we ended up with a total shift in his schedule. Later nap, and later BT. This was a kid that for his whole short life had been asleep BY 8 pm, no later. Well, now.... Not anymore. His nap is now at 2pm and his BT is 8:30-8:45(put down at that time), asleep between 9-9:30.
I realized that if I wanted to keep his nap, I had to accept the later times. So for now, we ate leaving it be, even though the BT is an hour later than I would like. Also, we throw in a no nap day in here and there, which gets a longer nap and longer night for a couple of days.
So, I believe that each child is different and requires different amounts of sleep, and some, though maybe not most, are really beginning to move near dropping the nap at this age.
I don't think I'd drop it totally. I'd start by moving the nap a few min for a few days. See if that works to get a better nap and maybe a later morning WU. We also had SA and fears at night and we just have lots of extra comfort in his room but didn't take him into our room.
So, now we have about 10-10.5 hour nights, sometimes 11. And an hour to hour and a half nap. Mostly 11.5 total hours of sleep in 24.
For us I think some was developmental, but some was moving closer to losing the nap, hence the shift in later times. Good luck! You'll find what works.
