So let me get this straight, your baby had been under water for a maximum of 10 seconds. She was kicking and had her eyes open. You screamed, grabbed her out of the water, called 111 and went to a&e.
My take? 1) Babies up to about 6 months have an automatic reflex called the brachycardiac response, which kicks in when submerged, which means they can hold their breath for short periods of time. www.livescience.com/20802-newborn-baby-skills.html. This starts to wane at 6 month but according to this study pubmed.ncbi.nlm.nih.gov/12022304/ remains past 6 months. 2) When children are drowning, they don’t kick or flail kick like in the movies, they are motionless and don’t show signs of distress. Sadly parents and caregivers not knowing this have let their children die right in front of their eyes. mom.com/kids/7973-what-drowning-looks/jumbo-gloss
This is the last sentence of the first article I linked. The survival response keeps babies alive a lot longer than adults would survive underwater. From what you’ve described, your baby was kicking and not showing the classic signs of distress as described in the last article. I’m actually thinking it is far more likely that the her brilliant body had protected her via the brachycardiac response and she was happily playing underwater for a few short seconds.
Of course if was a stupid mistake, understandably you presumed the worst, everyone freaked including your baby and you called 111.
As for why did you get told to go to A&E? Much as I appreciate that 111 will have told you to go to A&E, the person or people you spoke to could hardly say otherwise as they had no way of knowing without seeing your baby underwater what kind of state she was in and anything less than physically checking her over would have been negligent.
NB I say this as someone with no medical knowledge btw. But as a person, who has learnt through research and by experience how children react in and around water. My friend is life guard trained and I have had to get to know a lot about this subject due to my dds medical condition so I’ve asked a lot of questions on it.
I really do think you need to go and give your wife a big hug and tell her how sorry you are for freaking her out so much. I get why you reacted the way you did. But she’s feeling guilty for all sorts of reasons. And this is one reason she could strike from her guilt list. And if you both don’t get a grip on this situation now, she is a prime candidate for post natal depression (even if she didn’t give birth). PND would have a far far greater effect on your children than those 10 seconds and ensuing few hours ever had on them.
Bottom line. Lessons have been learned. We have all done stupid things and if either you, she or both of you cannot get over this now, I would urge you to seek some therapy to alleviate the anxiety.
