A sleep consultant I know strongly suggests parents introduce a blankie/lovey to their LO at around 3-4 months, and believes this will help them become better sleepers.

This sounds like a good idea when it comes to some situations like traveling with my LO, but I also witnessed my younger brother's attachment to his blankie when he was growing up and the drama it created when we had to wash it or if he left it somewhere, and I'm a bit hesitant to relive all of that with my LO!

Do your LO's have blankies, and do you find them helpful?
