We have a 3 months old

Getting my son on a routine was key for getting him to sleep through the night, which he did at 2.5 months. After a day filled with plenty of calories, activities, and naps he was ready for a good night’s sleep!

Plus, babies thrive on routines. They know what’s coming -- and so do the parents!

The predictability of a routine allows me to plan what I can realistically get done during the day, which prevents over planning and false expectations. As a result, I’m a much calmer and less-stressed parent!
