Riddle-me-Ree, Who can she be?

Greetings wonderful MTBs!!!
and good work to all of you!
For having solved the riddle before
I give you all this clue.
The letter " K "

Write it down, add it on...
And let’s move on to the next little song.

“A super duper chilled mom, sunny and bright
Adores her darling “firstborn” – that sure is right
Not one, not two, not three, not four
Tis six different blogs she hangs out at, por favor
A lady who likes to do tags when they’re “red hot”
A surefire thirst for blogging, she’s definitely got.”

Solve it and you get your lead
Misguess, and you lose your speed
Solve it slow but solve it now
And before you go, take a little bow

Go to 'Comments' and leave me a clue
Tell me which blog you are off to.
Good luck! Good luck! Be on your way.
You have your work, cut out for the day!
