Why do babys pooh there pants and wee themselfs and then it stinks?

Babies are incapable of walking to the toilet and going there, therefore they wear something us adults call nappies, and when the poop or pee us adults change their nappie so that they dont feel uncomfortable. It stinks because it is waste product. Be;ieve it or not u once wore a nappy- maybe you still do thats not for me to comment on but i do think you should grow up! Thanks for the 2points tho!
