When you have an inconsistent baby or toddler, every day is different. When that happens, it's easy to want to try to find the right "recipe" for good sleep. I remember trying to recreate exact days when my son, who inspired The Baby Sleep Site, slept well the night before or napped well. A successful bedtime routine is definitely something that is effective for many babies. In fact, if your baby is slower to adapt (i.e. not very "go with the flow") having consistency definitely helps a lot!
