Hello, I am in London at the moment, on friday we will go to Scotland but we actually live in Germany, our families are just all over the place so I know how it is to travel with a baby...
What worked for us is doing things that Scott (6months) recognised from home. Same bedtime routine, same toy, blablabla...
If she cries when you put her to bed try to pick her up and make a REALLY cheery face to make her happy. Try not to look worried or annoyed and stuff and do it together with your hubby.
