Puppy sitting, will it cause her too much distress?

Hi, I seem to be posting here a lot recently (first time single dog mom and my anxiety is off the chart these days lol). I have a 11 week old miniature poodle beagle mix and training has been going great.

Potty training has been great same with crate training! She barely has accidents inside, maybe one or two a day but mostly dry days! She has only been whining for a minute or two when in her crate and then settles until it’s time to be let out. I can leave her for three hours and she just sleeps until I get home. We’ve had no accidents in the crate for a while! Given her age I am impressed and could not be happier.

I am driving an hour to have my parents watch her for 5/6 hours, as I made a commitment to be somewhere. They are both very experienced with dogs and puppies, I do trust them and my puppy knows my dad and his dog very well.

I have a puppy car seat for the drive and a carrier for while she is there. I am packing her toys and her blanket plus her favourite treats.

I am just scared this is going to stress her out a lot. She’s fine with me not being around but I’m scared to how she will react to an unfamiliar home and some unfamiliar people/pets.

We are finally starting to connect and I do not want to ruin that

After I pick her up and bring home will she be any different or regress in the progress we’ve made or mad at me?

I am just overreacting and everything will probably be fine, right?
