I use full time cloth in hospital for both Findlay and Iona and it's never been a problem although one nurse has whinged a bit that a wet bag is an infection risk . Just put him in something that is Velcro as they may take the nappy off depending on which part the MRI is being done on and in my experience nurses/radiologists/nurses are generally incapable of managing nippas or poppers In my 2.5yrs of experience of using cloth nappies in hospital Easyfits/Teenyfits seem to be the nappy most managed by nurses.
Even if urine output needs to be monitored cloth is not an issue despite what some (not cloth friendly) nurses say, I've got a set of scales in Iona's room as she has to have her output carefully monitored due to being on TPN and as every cloth nappy weighs differently I just have to weigh every single one before it goes on and then when it comes off.
Hope the MRI goes well xx
