So actually, I couldn’t remember either, so I just skimmed IWTV, and neither actually happened quite that way in that book. But it’s still sort of canon bc Anne Rice wrote the script, and she was trying to incorporate later canon stuff where she could. 

In QOTD, Claudia mentions it in her diary: “Of course, he gave me a doll as usual, the replica of me, which as always wears a duplicate of my newest
dress. To France he sends for these dolls, he wants me to know. And what should I do with it? Play with it
as if I were really a child?…

They would crowd me out of my bedroom if I
kept them. But I do not keep them. I burn them, sooner or later. I smash their china faces with the poker. I
watch the fire eat their hair.”

[X] In IWTV, Claudia crushes a doll in front of Louis and she talks about being disappointed in baby dolls… she was pretty spoiled by her dads, so I would bet she got them at other times than just her “birthday,” too! Maybe the fanciest ones were received annually.

^The haircut thing is actually something Gabrielle experienced in TVL. She had cut it and the next night it had grown back to its full length it had been when she died:

Her long heavy hair had slipped over
her shoulders again, and exasperated, she took hold of it in both
hands. Then suddenly she made a low hissing sound, and her body
went rigid. She was holding her long tresses and staring at them. 

“My God, ” she whispered. And then in a spasm, she let go of her
hair and screamed.
