Can you understand your 3 year old?

My 3 year old is non verbal. Its usually just mama or dada. Then a bunch of sounds. Usually i can figure things out but most dont understand him

My daughters speech is pretty good but sometimes when she's telling a story the middle makes no sense. She will say something like, at nursery me and Amelia played and ... eisavisavisaehihbab ...mixing the dough for bread

I'm like ? What
