Hi Chell!
How long have you had your kitten? If it's just a day or two or even a few hours, she is probably scared about alot of things! Imagine how you would feel if you were taken out of your known environment and put in a completely different one, with new people, no other kittens, new toys, nothing that smell like the home she had & now there's new noises, too! She may be just adjusting, or it could be the noise of the fireworks? If, on the other hand, you have had her for a few days or weeks & she has adjusted to her environment & schedule, then is probably is the fireworks.
I foster so we get alot of fearful babies around here of all ages! When kittens whine, or talk to us, I just carry on a conversation with them in very calm voice, doing my best to soothe them... I tell them it will be okay, pick them up & rub them calmly & snuggle them closely, holding them as much as possible... it seems to calm them a little. When we really fussy babies we sit down with them allowing them to sit in our lap, snuggling & stroking with them, focusing completely on them... They will continue to complain, but will eventually slow their fussiness. When we get little babies, we hold them close to us, on our chest and pat their little hind ends, like a baby - believe it or now it soothes them, at least enough to get a bottle into them & then they stop complaining & see that we are working with them and for them!
My best suggestion is to keep a regular schedule with your baby, she will learn to expect it and that will become her comfort with you...
I know this probably didn't help, but I hope by now she is settling in? Do let me know!
