I had all the sunshine goodies as a child. There was also a red curly hair toddler called sweets as well who came with her own baby gear. Your dolls look accurate. The mom had a printed maxi dress with a white pinafore apron.
The dress, apron, and shoes on your haircut doll are all Stephie’s original outfit. You should redress your good doll in that so she will be complete. The outfit she is wearing is a put-together, non-sunshine family outfit. The Grandparents came with hair color variations of white, silver/gray, or blonde. Some of the Grandma dolls have mixed blonde and gray, so there are a lot of variants. The second Grandma’s head is on a body from a World of Love doll made by Hasbro in the early 70s. The Sunshine Family dolls, fashions, and play sets came with crafting booklets that gave ideas to repurpose milk cartons/tissue boxes/toilet paper rolls, etc. into furniture and accessories to enhance play. Their fashions included outfits to decorate with beads, stencils, ric-rac, yarn, and such. They had a Jeep car with a Craft Shack on the back, two different home play sets, a Craft Store, a Farm set, a Greenhouse set, and a pets set that included a pet house with a dog and a cat.
Your Haircut Steffie is actually in an early long Apron. Very desirable. There were three waves or issues of the first family of three with Mother's dark floral dresses. The first wave had a long apron with working pockets and generous wide shoulder straps. The Dad that goes with the first wave set also has pockets on his pants. Those were only issued very early and were quickly replaced by the same outfits without pockets. That's what you have in the cut hair example. She's in great shape except for the hair cut. The Dress has a separate skirt and long sleeves on both the second and first waves. The third wave Steffie has a shorter dress with shorter sleeves and a shorter apron with more narrow shoulder straps. That's the most commonly found of the dark dress moms. The following year the dolls were reissued in Red White and Blue themed outfits as they hit the market in 1976 and it was the country's big Bicentennial celebration all over the nation. They stayed in those bicentennial outfits until the end of the decade when the Baby Sweets turned into a toddler and had a new baby brother with freckles. Their outfits and home lost their country beginnings and they moved to the suburbs into a two story townhouse (very rare house!)
Hi, the doll with the different body is a hybrid doll. It has the grandma head but by the looks of it she has been attached to a skipper body. There were no changes to the body style - all females had the same body. Mostly likely replaced due to damage to the original body. Great dolls though - I love the Sunshine's :-). And you are correct with the outfit for the last doll - the outfit is not original. No doll brushes came with the original dolls but there were a whole range of accessories that came with them though including a Pet set.
The issue you notice with the eyes is called melt. It happened because the plastic of the eyes negatively reacted to the chemicals in the vinyl. All of the early dolls eyes melted. Mattel must have realized the issue because less of the middle bicentennial dolls eyes melted. And the much later dolls eyes seldom melt. Bodies on Sunshine family also have melt issues with the vinyl parts. Youll see allot of that! But every once in a while you can find a body that was produced by one of the other factories where the formulas for vinyl and hard plastic were more stable. Those are a sweet find so be on the lookout for those bodies. You will know them right away because the arms and head turn easily with no "sticking" and there are no areas of goopiness or melted looking joints.
I think their just darling. I really like them. Im surprised that ive never heard of them before. I just love the grandma, her hair is fixed like a grandma, kinda like a bun. I think all of them are in great shape and i think you could fix their hair. Thank you for sharing them
