Laundry care in case of baby clothes is not a simple thing. The skin of the baby is very delicate and sensitive which calls for extra care and attention, especially in case of clothes which are in direct contact with the baby's skin. Thus you should preferably go for natural laundry baby detergent which is very gentle for the clothes, safe and chemical free as it would be good for the skin.
