Recently I drove through the mountains with my exclusively-breastfed 5 month-old. She has never taken a pacifier, so I didn't know what to do to help her ears adjust to the pressure. I wished that I had one of those pacifiers that you can use to dispense medicine! I could've hand expressed a little breastmilk into it, and then passed it back to her. Sure enough, I tried it after we got home, and it did the trick to calm her down from a crying fit (she's teething) in the car. Of course, you should only do such things when other people are driving. I thought other moms in the mountains or on road trips might be able to use this hack.
It's really hard to let down for a pacifier, but when your baby's screaming, it's a little easier!
