Frequently Asked Questions
What are the 4 stages?
Stage 1 is a newborn hammock sling that keeps baby suspended at a safe recline. Stage 2 removes the sling for reclined infant bathing. Stage 3 props baby in a sitting position. Stage 4 converts to a seat insert for your regular bathtub.
Does it fit in the kitchen sink?
The tub is 31 inches long — too large for most kitchen sinks. It's designed for use on a bathroom floor, inside a regular bathtub, or on a counter with supervision.
How do I clean the mesh sling?
Rinse the sling after each use and hang it separately to dry. Mildew can develop if the sling stays wet inside the tub. Some parents handwash the sling with mild soap weekly.
