Query: Cute, but dysfunctional

We bought the Frog and at first it seemed great because it is quiet and cute, but every night for the first week, it has stopped working in the middle of the night and as an already sleep deprived Mom with a newborn, I have been up multiple times a night fixing it. For reasons I can't figure out, even though the water level is normal, the adjustable dial is at medium and everything is set up right, it just stops working, causing the red light to go on and for it to make a different noise that wakes me up. I jiggle it a bit, lift the top part up and put it back down and it works fine, but I would only buy this if you don't mind getting up a few times each night to make it work again.
