Help! 2 year old suddenly can't sleep

[Livy'smom]

My 2 year old makes up excuses to stay up  very often now.  She has a 2 month old brother and she is recently potty trained. She prolongs sleep by crying for us to take her to the potty, or that she already went potty in her night diaper.  She may cry for water, books to read, or to get rid of books or a blanket in her bed.  She cries loudly and screams for or us.  It happens when it's time to go to bed and in the middle of the night.  This happens at nap time too.   She has always been a terrific sleeper.  Sometimes she would wake up and cry in the middle of the night, but when we wouldn't rush in, it stopped.  Now that she can talk well, we would give in to what she wanted.  Now what?  How do we get her to go to sleep and not ask for everything?  What things should we go in for, and what not?  Help!!

Is she untired? Getting ready to drop her nap?
What's her routine?

My son dropped his nap at 2. With naps he was no longer falling asleep before 9pm.

This probably won't really help you but we are going through the same thing here. He went from being a completely independent sleeper to needing us nearby-usually sat outside the door going "shhh". It started when, without warning, suddenly increased A time to about 6 hours. So initially, I think he was just undertired and he's never been one for just chatting in his cot before going to sleep. I know think its become a bit of a habit but I also think its largely SA too. I have to really time bedtime to perfection. If he's undertired or overtired then he is much more demanding.

Perhaps try increasing A time by 15 mins or so to see if she is more tired and less resistant.
