Napping outside of home

Je

Ok so I do occasionally visit my friends. For whatever reason though,baby will not sleep at anyone's house.

I know it's because it's different environment and it throws her off.

So like anywhere I go she won't sleep until she gets in the car.

Is there a cure for this?

Interesting thing is at my mom's she will sleep because there's a pack and play there and a dark quiet room. So that's her environment she needs.
