It’s useful to remember that all babies and toddlers wake 4-6 times a night. They ‘sleep through’ when they can get back to sleep after each awakening without your help!
If you use a bottle or breastfeed to get your child to sleep at bedtime, over time this teaches your toddler that they need the milk to fall asleep…..
Then when you again use milk during the night, once or several times, this constantly reinforces to your toddler that they can only get back to sleep with milk!
So rather than become less likely to wake, your toddler may in fact begin to wake wanting a bottle more frequently – until the point you decide not to use milk as a resettling technique.
