Does anyone have any advice on helping babies adjust to sleeping in a different environment. DD is 7 months old and sleeping through when at home. The trouble is i visit my parents at least once a month for a weekend as they live away. DD will not sleep through when we are there. They have bought a cot incase it was her travel cot she didnt like with not luck. She follows the same routine goes down awake but will not stay asleep. Anyone with any ideas?
