Hi. Until what age shld i expose my baby to mrng sun?

Now days people hardly go under the Sun fearing the harmful effects of the ultraviolet rays. But morning rays are good source of Vitamin D, and should be good for baby's growth. But you have to be sure to let him be out during the morning or evening at the time it is good and not vary the timings. It should be around 7 to 8am for 10 to 15 minutes. http://just-share4u.blogspot.in/2011/07/bask-15-minutes-in-morning-will-give-so.html
