OK this is what I can remember... I believe the movie is from the early to mis 80's
There was a girl I believe she has two sisters and she is at this little cottage where her and her sisters are watching these babies and the babies get sick and vomit... I also remember a well and a guy singing either to the girl or about the girlwhile he is at this well . And the girl also I believe has a cat

I think that it might be little women but I'm not sure

I am now pretty certain that your movie is the 1976 German animated film Once Upon A Time (http://www.imdb.com/title/tt0075011/). Here's what one imdb.com reviewer remembers of it: "...the evil stepsister Mary Lou demanding the garnet stone from Maria by clapping her hands twice and holding out an outstretched hand, the totally surreal scene with all the babies being fed by Maria and Mary Lou, when they break out into song in praise of Maria (something like, "MARIA, MARIA, YEAH YEAH YEAH YEAH YEAH!! " It also features a prince and a magical well.
