A little history before I go into what happened:
In December 2012 our baby girl died in-utero, it was shattering. In February we welcomed our rainbow, a gorgeous, healthy baby boy. Because of the loss of our daughter I have a lot of anxiety about loosing our son so we have a couple breathing/movement monitors for when he's sleeping, a Snuza that clips to his nappy and then a monitor under his mattress. I had stopped using the Snuza a couple months ago when it started to warm up because he was getting a little heat rash from it but since it's been hot and we need to have a fan on in his room the fan sometimes interferes with the cot monitor so I have the Snuza on as a precaution.
Last night he woke at 9.30 for a feed, I fed him and laid him back down to sleep in his cot. I went back in about 15 minutes later to sleep (I sleep on a bed in his room). About 5 minutes later his Snuza went off. I was scared but thought it was just a false alarm so gave him a little shake and said his name. Nothing. Picked him up and kind of shook him and still nothing. Then I ran with him screaming for my husband into the hallway and put him on the floor to do CPR. It was dark until then and then my husband turned on the hall light. He started blinking his eyes to the light and crying like I scared him. My husband thinks the Snuza fell off and he was just in a deep sleep, his cot monitor started alarming by the time we were in the hallway, so a few seconds after he got lifted out of the cot. But I don't know whether to trust that because it sometimes doesn't go off with the fan on (from testing it). The snuza was off when I unzipped his sleeping bag but I don't know if I did that in my panic or if it was already off. I could have shifted it slightly off during his breastfeed, I didn't check to make sure it was still in place before lying him down and then he moved a bit before falling back asleep.
I'm so scared. I don't know what happened, if it was a false alarm or if he really stopped breathing. I feel like I've barely survived loosing our daughter, I don't know if I could survive loosing him.
He seems fine. He chatted himself back to sleep when everything calmed down. Chatted back to sleep again after his 4am feed. He's having a nap now but was playing this morning as usual.
Should I take him to the GP or the hospital to be checked? I don't know what I'm meant to do...
