The listings show baby swings suitable from newborn up to about 9 months, while unicorn rockers are listed for children aged 3 years and up.
Swings include a 5-point harness for secure restraint. Unicorn rockers list a stable frame with a high back and easy-grip handles to help support the child while rocking.
Some listings indicate no batteries are required. One portable swing requires four C alkaline batteries (required, not included).
The swing provides automatic sway settings with six speed options, 12 soothing melodies, multiple recline positions, and timer settings for 30, 45, and 60 minutes.
One listing explicitly states it “Meets ASTM Standards.” The unicorn rockers’ product details do not clearly list certifications.
