New puppy home for 5 hours and hasn’t played/drank/peed

Bought our 10 week old puppy home today and like the title says, she hasn’t done anything for 5 hours, just slept on our laps.

I visited her twice with mum and the rest of the litter, and both times she was playing and had lots of energy. Breeder sent picture/video updates regularly and she was playing/exploring/growing normally.

She has been to the vet and had microchip and vaccinations, apart from a small umbilical hernia there were no health concerns reported.

Is she just decompressing after a big day?

Thanks
