Hi and welcome
I am so glad things are working for you, i think you find this is the case w/ BW'erering!
That is a tough one and i have been there many times. What i did was do my best to keep her awake until the next nap. But also take into consideration a few things:
-how long is that from last waking? is it realistic for her or will she be totally overtired?
-if i put her down early, what time will it be till next next nap or bed time? Is that realistic?
Sometimes i would split the difference to try to save the rest of the day.
Does that make sence?
Hope that helps. Hang in there!
