Looking for a book from about 1960 about a young teen girl. Her mom makes all her dresses, but she wants to babysit for extra money so she can buy “separates.” She babysits children who come down with diphtheria and she must work hard to save them while in quarantine. Good luck!
Parents go out for the evening to opera (Madame Butterfly?). The child(ren) cope(s) with a babysitter. I think the babysitter is referred to as the onion lady and she wears many layers of clothes?? circa 1970’s.
