Hi,
Sending well vibes to Freya.
Just to add to what KellyT said, they couldn't 'feel' the milk bottle lid that Florence swallowed recently- it was stuck in her tummy, not causing a blockage but causing stomach agitation as it was too big to pass through or for her to sick up. They did an ultrasound as x-ray doesn't show plastic and then removed it via an endoscopy. If it does go down this route, I just wanted to offer some reassurance, that Florence was absolutely fine after hers, she was a bit tired from being knocked out but the next day was 100% right as rain. (she has got a dodgy hair cut mind where they shaved her tum for the ultrasound!)
Hope she's feeling better soon.
