Hi kitty, I'm following along with your thread. My DD is 17.5 months old and recently I"ve noiced she also has started doing the similar thing to your lo. Our 2hr 1-nap day routine which was great for about 1.5 months is also getting a bit wonky now.
On an ideal day our routine is:
Wake up - 6:30
nap - 12 - 2:15ish
bedtime - 7:30
We had a few odd days last week where she would only sleep for 1.5hr at nap time so when I put her to bed earlier (like say 6:45 or so) she would wake up at 5:30/5:45 the next day:(
I'm curious also to hear what others say.
Hope you get a sleep in tonight! Isn't it always something with our LO's? You think you've made it to 1 nap and breath a sigh of relief and then BAM something else changes!!
