What are some tips you used when your infants wouldn't stop crying, that worked, that you'd like to share?

My daughter gives her 7 month old twins beef jerky when they won’t stop crying. They’re not wet, they don’t want to eat, they don’t want to sleep, Mom’s pulling her hair out…but if she gives them beef jerky it’s like a miracle. They love it, love it, love it. She gives them the super dried, really thick slices. It tastes good, and it has just the right amount of rough texture that feels good on their gums, and has that tiny bit of give to it when they bite down. They’ll chew on them all day long.

I think this is something everybody should know and pass on! I’d also like to hear your results if you every try it.
