I have bough every course that applies for us so far and all have been extraordinary! The first five month bundle helped us understand what our day could look like and got us out of the newborn fog. Then we started sleep training at five and half months and my daughter who had a tough four month sleep regression quickly became a spectaular sleeper - all with very little tears. We are so grateful for the wisdom we have learned and that we are in a good rhythym with everyone starting to get enough sleep. I am sure I'll be back buying the toddler bundle here soon.
