We are B”H parents of four young boys.
All of them were trained from 8 weeks!
There is a book written by Gina Ford, where she gives full “instructions” on how to get your baby into routine, enabling him/her and the parents to get a full nights sleep.
Yes I know a baby is not a machine where you follow instructions how to use it, but the facts are that we tried it on 3 out of four kids, AND IT WORKED!
It is hard to keep to it, but beleive me it is worth every penny of the book, and every difficult moment to reach the target of a decent nights sleep, making your home a more calm and peaceful place with less tension.
This is primarily useful for the average child in good health.
It probably wont help on the occasion when a child is sick or with a child with needs.
Wishing everyone much nachas from all their offspring, gezunteheit.
