Nicole - I'm sorry I didn't see this earlier....when did Hayden get to be 14 mos?
goodness how the time goes! I'm going to pop this over to Toddler sleep for you - though I guess you could do it yourself
I would cut back that afternoon nap a bit - I suspect she's waking early because of the long late nap. Try just 15 min earlier on waking and see if that helps. Abby was always on the high sleep, low A time end, and at 14 mos, she just made it to 1 nap but was getting about 3 - 3.5 hrs of day sleep and a 12 hr night. Before the most recent EWs - how much day sleep was Hayden getting? I'd try to keep her total day sleep to that amount, so wake accordingly from that pm nap to balance it out with the 45 min am nap. Does that help?
