Using this baby stroller is easy. First, unfold it and make sure all the locks are secure. You can adjust the seat to either the sitting or lying position according to your baby's comfort. When taking your baby out, put your baby gently into the stroller and fasten the safety belt. Remember to check the belt regularly to ensure it's tight enough. For maintenance, keep the stroller clean by wiping it with a damp cloth regularly. Avoid using harsh chemicals as they may damage the material. When not in use, fold the stroller and store it in a dry place. Make sure to check the wheels and shock - proof parts from time to time to ensure they are in good condition.
