I started using this tub as soon as my son's umbilical cord fell off. The sling worked perfectly to lay him deep enough in the water to be warm, but not be totally submerged. I realize what other reviewers are referring to when they talk about a "bump", however my baby has never seemed to feel discomfort from it. He loves his baths and is perfectly content to hang out in the sling as long as the water is warm. He is now three months old and I still put him in the sling, although I will probably transition him out of it soon. I use this tub inside my bathtub so to drain it I just turn it over and dump the water, I don't mess with the plug. This tub does come with several toys, but I haven't used them yet. Overall this tub serves its purpose and keeps my baby safe and cozy while he's in the bath.
