I wouldn’t sweat it. I used to compare things that other people’s babies did to things my dog did (I did these things when I was previously childless). Looking back I used to cringe a bit. But now as the proud owner of a 2.5 year old son and another on the way, I can honestly say it offends me zero percent when people do things like that. I would have found your comment hilarious and in no way offensive. You just keep being you.
