From research on kibbutz infants' attachment to mother and metapelet: "Results indicated that children protested equally to either mother or metapelet separation when left with a stranger." (source)
"Are you looking for a metapelet who will come to your home or who will watch your baby in her home?" (source)
"The metapelet wants to know if you mind if she tunes in to a Mozart concert." (Glinert)
