Query: Cheap and easy for us, difficult for babies

Bought this based on other reviews and figured for the price of a coffee and cookie if this didn't work it wouldn't be so bad.They fit snug, so you have to use some force to pull them out. I was afraid a couple would fit loose, but all fit snug. They're clear so can't tell they're on.Love it. Recommend it.
