Hi my memory is pretty vague. What I remember is three kids lose their mother. They talk to the gadener next door (older lady) and she shows them how to shop for a new mom. They go down this alley where they can pick a new mom. They try out all these perfect moms but none of them seem to fit or take the place of their mother before. That's about it, if anyone can help please respond!!

I reckon it might be this here one:
