Some people prefer to use bar soap to massage directly on the baby’s skin or to lather in a washcloth for use. As mentioned by a few customers online, it takes two hands to lather a bar soap into cloth, so it is harder to use than a liquid soap. Bar soap can be used to massage the baby during the bath directly, where a liquid soap cannot. This is why most people prefer a bar soap over a liquid soap that must be applied with a sponge or cloth to be used properly.
