Did I find the Magic CD Combo? Baby sleeping 7 hours!

Our LO typically woke after 3-4 hours during the night. A few nights ago, we put a Grovia doubler underneath a Flip insert and she slept for 7 hours! The next night, we didn't have clean Flips, and she slept the typical 3 hours. Then last night we did the Grovia/Flip combo again and AGAIN she gave us 7 hours. Maybe it's coincidence, but I'm going to keep up this combo for as long as I can.

Does anyone else have recommendations for keeping baby dryer, longer?
