I just started using the Snuza Halo about 10 days ago. Last night, lo was wasn't wearing a onesie under her nightgown. She slept from about 9 or 10 until 5:30 AM without incident. I fed her, changed her diaper and laid her back down. We got up at 7:45 and at about 9 when I went to change her diaper I noticed it was flashing red!!!! So sometime between 6 or 6:15 until 9 it vibrated. I am so anxious and it is depressing me. I keep trying to tell myself that it may have just lost contact because of the diaper or how she was positioned after we woke up. However, I can't help but worry that she had an apnea episode or whatever. Anyone else use the Snuza and have it go off or flash red? It is scary. I don't go into the pedi for another 8 days to even mention it to him.
