I think Dr Michael Carr-Gregg makes an important point (though somewhat indelicately) in his recent interview with the ABC:
I have a bit to say about this issue in “Your Cherished Baby”. This is a short excerpt from the chapter on toddlers…… Young babies cannot be spoilt. For the first few months they rely on their carers so completely that it is hard to imagine a baby being cared for too much. The baby’s the boss and needs absolute security in all aspects of his life, and there is no danger in him learning ‘bad’ habits.
