No my kids don't mind my singing it's my dancing they hate lol. Enjoy your youth you'll be old just like us one day and your kids will be dissing you lol.
Some of my happiest memories are of my dad and I singing in the car. We didn't get along that much when I was growing up, but we did like music and we both could carry a tune.
It might seem annoying now, but you might just miss it one day. Just saying. :-)
My parents sing on a daily basis but they both have good voices and dont sing very loudly so it doesnt bother me that much until company comes over.
