I would like to add however.... you say your 2yr old doesn't have tantrums? You say this like it's a good thing? Well, it's quite NORMAL for 2yrs old's to have tantrums anyway did you know that?
According to Dr Margot Sunderland (a well known child psychologist)..... "the too-good child who does not have tantrums may have learned early on that expressing big feelings elicits a frightening parental response, and that the price of parental love is total compliance. She explains that the too-good child misses out on vital brain sculpting, meaning that when he faces frustration in later life, he may respond with angry outbursts or struggle to be assertive.
LOL I find it hilarious that we just can't win. We are damned if our child misbehaves and damned if they're well behaved too!

I personally think tantruming can be a personality thing. My DS didn't tantrum as a 2yr old.. we BREEZED through the 2's with him! I know other 2yr olds who have been gentle parented (more gentle than us!) that were quite delightful and content. Turning 3 was another story tho Boy did we discover attitude! LOL. Both my kids are parented the same (well.. as in same philosophy.. definitely no CIO so can't blame the 'good' 2yo behaviour on him not feeling heard) and we've now got a tantruming 2yr old little miss LOL. I really do think personality and luck of the draw with that plays a big part.

MantaRay - great post. I agree with what you have said re frequent waking and breastfeeding. If there is one thing I like to tell new mums.. it's that it's ok for a baby to wake and feed... for MANY months. People seem to have milestones in their heads.. like 6 weeks or 12 weeks.. that that is when their baby should be sleeping through. I like to get it out there that these babies are RARE. And yes... i agree it is very dangerous to be encouraging sleeping through (as in 12 hrs!!) for newborns. Very detrimental to breastfeeding

One thing I remember from the ABA breastfeeding class was they said not to take breastfeeding advice from anyone who hasn't successfully breastfed. I would say it's the same for parenting... why take parenting/baby advice from anyone who hasn't ever had a baby??
