I also remember reading in 'What every parent needs to know' about what happens in a baby's brain when they are allowed to cry for an extended period. l.
depending on how they are allowed to cry & the reason why

if zander is upset he wont feed if he is not hungry - that is his choice and not because i am refusing to comfort feed him. he also doesnt feed to sleep - again his choice - babies are individuals and will respond differently.

as jennifer said - its what is working out for your family - and when there are other kids sometimes everyone has to wait at times even me!
