There is an internet encyclopaedia which offers well written information about early childhood development:
ENCYCLOPEDIA on Early Childhood Development
Parents aiming for shared parenting will usually benefit from a better understanding of child development. I would suggest that all parents would benefit from a better understanding of this topic.
I have a USA Parent Skills Programme, of self paced learning available for loan. It is based primarily on negotiation and understanding and management of available incentives.
Although it does take determination to follow through, I support this system because it practically and directly faces the realities of somewhat reduced parental authority these days and it incidentally assists with spousal and/or familycaught$ negotiation. This latter may be a significant assistance for many parents. I don’t enjoy the accents, but the content is good.
If you are interested to try this programme out, give me a call on (09) 638 7275.
