This seems an excessive amount of judgement for missing calling her son at bedtime. Your standard seems unreasonable.
When my kids arent with me, I dont contact them unless theres something urgent or important. I dont think that makes be any less of a parent.
Id urge you to really consider your thoughts here regarding this multiple times daily facetiming. Yes, it's only 5 minutes, but I wouldnt think a 3 year old would have any interest in facetiming for several minutes at a time multiple times a day. It seems like more than just your S talking to the other parent, to me.
