My 9 yo daughter is having a gastroscopy soon. I think we have all the main info and DD is now feeling okay about the procedure after a good chat with the doctor. She has asked me how long she’ll need off school. I assume she’ll be well enough to return the next day but I wondered if I’m right with that? I’ve read some stuff online saying to keep a close eye for 24 hours. Would I be best to keep her home the following day? Thanks.
