What works one day might not work the next.
The only thing that remains consistent about parenting is change. This should come as no big shock, because, if you notice, life, itself, is always changing. Every day. All the time.
The developmental phases that we coo and fuss over, will transform.
The habits and behaviors we can’t stand, will not be the same forever.
What works, might work for a while, but then the child’s needs change, and so you have to change your approach.
