This baby rattle toy set is designed with safety in mind, crafted from baby-friendly materials and featuring rounded edges for secure handling. The gym-themed rattles come in dumbbell, kettlebell, and barbell shapes to encourage movement and interactive play between parents and infants. The bright colors and gentle sounds help stimulate auditory and visual development while supporting fine motor skills and hand-eye coordination. The barbell piece and sports bottle straw double as textured teethers to soothe teething discomfort. Suitable for infants 3 months and older, this set makes a practical gift for occasions like birthdays, baby showers, or holidays. For cleaning, use a damp cloth or wet wipes—avoid steam cleaning or prolonged soaking in water.
