Having your children on a routine is key to success !!! Research shows the children thrive on structure and routine and this doesn’t just start when they are school aged. It starts right from the get-go !!!
A book that really helped me out in the beginning is a book called The Baby Whisperer. I found it helpful because it was more of a guide book that helped me create a schedule for my kids. She also breaks down the stages of development and how to change with each stage.
For me, breaking things down into segments has always been a strategy I have used to get through roadblocks and nap/bed time were definitely a struggle for me at times.
