5. Operating Instructions
Follow these steps for safe and effective use of your Mastela Baby Rocker.
5.1 Securing Your Child
- Place your child in the seat.
- Fasten the 3-point harness. Ensure the straps are snug but not too tight, allowing for comfortable movement.
- Always double-check that the harness is securely fastened before leaving your child in the rocker.
