Possible termination coming

[Sassygirl]

I feel for you.
I have been there with all of my toddlers at some point.
Honestly? If she is fine otherwise all except for napping... Put her in the room furthest away from the others, it may be in a room you don't want to use but this will only be temporary until she sleeps better... Invest in a good set of blackout curtains and a white noise machine (I have 5 all bought from Superstore, made by Conair $24.99 and worth every penny!) and let her go in the afternoons. Do not go to her at all until your nap period is over and with the white noise machine on she will not disturb the others. I have a dcg who is a screamer from time to time despite how tired she is and I have another white noise machine I put in the hallway outside her room as well to block out all of her noise,
What time is her drop off and pick up? If she is arriving early she probably needs an hour in the morning still. Usually an hour max after drop off is when I do morning nap so here its 8/8:30-9/9:30. I wake them after an hour. Afternoon nap is a must here which is 12-3 but they can get up after 2 most of them have to get woken at 3.
If you stick with it she will become a great napper! Usually the ones who seem the toughest at naps when they start are the ones who turn out to be your best nappers once you get firm with them.
Good luck!
