A child may be able to say a word or phrase well in a relaxed setting but, when he is put on display and asked to  Tell Grandma..., the plan for saying that word or phrase is not accessible, and the child fails. Children with DAS may also lose words.
When applied to the surface of the skin or as a hair dye, henna is generally safe for use during pregnancy. Select your dye carefully, and make sure that the dye you are using is 100% natural henna. Natural henna stains the skin orange, red, brown, cinnamon, brick, chocolate, or coffee, and can last about one to four weeks.
This gradual darkening of the stain is a sign that the henna paste is 100% natural! I strongly recommend to get the Henna tattoo at least 2 days before the Wedding or occasion so the stain reaches to its peak color. It depends on you how well you take care of it to make it last longer.
