Twinky-Winky (Dobby and Winky's child)

Guys could you please, please comment!!! I need to make sure it is worth continueing :/

Snow was falling lightly on the crowded Grimmauld Place. It was the first time it had been occupied for a long period since the Dark Lord's downfall and the Fidelus Charm had broken. The house was filled with glowing yellow and red lights, Christmas tree branches broken along the floor. 

"Rose! James! Don't do that!" scolded Hermione. The two children took no notice and continued to break and scatter the branches. In front of the fire Ron, Harry, George, Bill and Neville were downing their firewhisky while Luna Lovegood was scincerly talking to Fleur about the Ministry of Magic. Ginny and Angelina were upstairs were upstairs, tucking the little ones into bed, Albus throwing a tantrum as it was too early to go to bed. It was so loud that its a surprise Rose and James heard the little knock through the din. James reached the door first, standing on his tippy-toes to turn the heavy handle. The sound of bawling filled the corridors of the house, the adults came rushing forth and the portrait of Mrs. Black was shrieking. Then as soon as it started, it stopped. Albus was leaning over a pile of blankets telling it 'Shush!'. It was with trembling hands that Harry Potter picked up the bundle and read the untidy scrawl:

"Dear Potters,

Last night, the house elf known as Winky died. The rest of the house elves say that  her last wish was for her daughter to come to you. This is Twinky- Winky, five years old in elf years, born ten years ago and the daughter of your friend Dobby.

A Merry, Merry Christmas and hope to see you soon,

Hagrid."
