Best comebacks to comments about family size?

Chelsea • Homeschool mom due with #5 in December, miscarriage between #2 and #3, follower of Jesus Christ

So far (pregnant with #5) these are my favorite:

"You sure have your hands full" -Better full than empty OR Yes, full of blessings

"You have a lot of good helpers today"-They are wonderful every day

"Haven't you figured out what causes this yet?" Yes, and we like it! ;)

Still haven't figured out a good/kind comeback to the guy who stopped me to tell me I was crazy, rolled his eyes, and then just walked away. (I just chuckled and finished my shopping... Lol)

Please add yours below! :)
