We’ve got DS12 (not my DP’s) and DSS17 all week. DP is at work so thought I’d take them out to an activity this morning. Both wanted to go. The activity involved puzzles which my DS wasn’t great at. DSS17 was saying things like ‘what are you actually doing, you melt’ and ‘how did you get that wrong’. At the time I reminded DSS17 that DS is only 12 so might not be as good as him. He generally spoke to him like that for the whole activity. The two boys usually get on pretty well, but my DS said to me afterwards that he felt a bit sad about it.
AIBU to mention this to my DP? I don’t want to ‘tattle tale’ as this may be a one off but it wasn’t nice to hear.
