Silicone baby spoon feeder is very useful for baby's who is weaning from breast feed to food from 4 months! one can give purees, soups, khicdi and any liquid form before your child gets teeth! I used this for 5months and now baby is 17 months old and I dnt require this! just boil it before use! the green cap doesnot need to be boiled! as per ml one can fill in the food and close the lid and feed with its spoon
