I feel dreadful - my son expressed that my mother shouted at him and scared him the other night when they were staying over babysitting. On the phone she explained that he kept getting out of bed (he is only 3) and she couldn't let him run around all night (granted but we usually place him back in bed, say very little other than - it is your bedtime, back to bed etc.) - I wanted to check that they were ok, and didn't find babysitting too much - they assured me all was ok, and we chatted about something else.
However, 10 mins later I get a call from her, she is extrememly upset and asking me why I even needed to tell her this - this then turns into a whole night of calls and messages about how awful I am and ungrateful etc... Things really escallated!
TLDR - AIBU asking my mom if she shouted at my son after he expressed this to me and said he was scared.
