Before putting your baby to bed have some quiet, calm cuddles. Try to put her to bed whilst she is still awake, but sleepy so that she associates going to sleep with being in bed. It’s normal for babies to grizzle when they’re first put down so try to give them time to settle.
You could pat, stoke or talk quietly to them to help soothe them a little more. Some baby’s need to be rocked or fed to sleep, this is also fine but may mean that you will need to do this when they wake in the night as well.
When your baby wakes in the night try feeding quietly, changing their nappy and settling them back to sleep, avoid too much stimulation.
