Your baby is awfully attention-seeking, isn't she Pawpatrol!
I mean, I thought mine were bad enough for both needing operations before they were 2mo (both had L inguinal hernias that needed repair before they became strangulated), and then DS2 just had to really up the ante afterwards with episodes of non-breathing as well!
Mind you, one of the GPs I saw put me straight about then 3yo DS2 - she told me I just had to speak sternly but kindly to him as he wasn't breathing and tell him not to be so silly before he passed out, and then he wouldn't do it any more - because that's what she'd done with her rather-older son when he started breath-holding. ACTUAL breath-holding, as opposed to crying all his breath out and then being unable to breathe IN again. My blessed child would then pass out and, unlike what they tell you in all the stories, would NOT immediately start breathing again, OH no. Luckily he did grow out of it once he passed 4yo - he hasn't done it since - but it was great fun having to write an Action Plan for his pre-school, and an accident report for the day he face-planted on the concrete path at DS1's primary school at pickup time, causing huge alarm among all the other parents and half the staff - attention-seeking, obviously!
AND, as if that wasn't enough, once he'd grown out of that he only went and got appendicitis earlier this year! Not obviously, mind, he was just a bit nauseated, a bit sick, no temp, no real pain, nothing you could pinpoint; until I decided I didn't like his symptoms, took him to A&E (Australia) where they eventually managed to get a drip into him - MORE attention seeking, with the fugitive vein thing he has going on, needed FOUR doctors before any of them could get a line in! - and he was taken to ultrasound where they discovered his appendix was rather large and in the "wrong" place (retrocaecal). When they took it out it was black with gangrene...
SO I sympathise entirely with your issues with your 8mo!
(and obviously hope that they sort out what is going on with her really quickly and start to manage whatever it is - you must be on your last legs with worry and lack of sleep! Huge unMN ((((hugs)))) to you and your family
