once in a while I use baby carrier for my baby and many times people say is not good, but ofcourse they dont have a any reason until a today a lady says it affects the scrotum of boys. how true is it,someone should please explain

I dont see the basis for any concern....after all they go onto ride bikes dont they? Ive googled it but havnt found anything, nor have i ever heard such a thing. And carriers are used a lot around the world for that matter. And babies are not even long in it really. But if you feel concerned still you can get the sling type of carrier, thats were the baby lays in it...and you can see you and actually they are easy way for a young baby to sleep, hearing his mothers heart beat and voice. Hope this helps your concerns

I have found article that it is not healthy. But not all of them. baby carriers like beco, ergo and wraps are better option because it imitates the sitting position. And its also the closest to the African way of backing babies.
