ELI5:Universality of the term "mama".

Every language I know (Arabic, English, Spanish, French, etc..) have similar terms for mother (madre, mere). Not only Latin languages, but also Arabic term is somewhat similar. Aside from that, every baby uses the word "mama" for mother and "dada/baba" for father and these are quite often their first words. 

ELI5 why "mama" is all so universal, even if the languages are so different from one another?

the transition from closed mouth to open mouth sounding is one of the simplest phonemes. Since children will mmmaa mmaa mmaaa, and mothers respond to their childs noises...mama becomes a word when in fact its only noise...but words are just noise assigned meaning. Another common sound caused by forcing sound through closed lips Ba give us BABA for bottle....the use of the tongue to form D generally puts dada later.
