Your baby will probably also begin to eat less at night around this time meaning they should be sleeping longer stretches. It’s important to keep in mind that your baby might be using eating to self-soothe, so watch out for this. Remember, there is no time limit on this whole sleep training thing though! The only issue you may run into is your toddler being a bit more defiant than a baby would be. It’s never really too late to sleep train though and you should do it when you and your little one feel ready.
