comment At what age or developmental milestones is a child capable of critical thinking?
Are you looking for child development stages as described by Piaget and Vygotsky?

Thanks. All those medical physics courses paying off :)

comment Any way to prevent bedwetting before it's actually starting?
Are you expecting chronic bedwetting as a condition, or bedwetting that happens when potty training? For our son, I've noticed that making sure he doesn't drink before bedtime is the biggest determinant to whether or not he wets the bed, or his nighttime diaper-- but your question suggests a more chronic (perhaps psychological?) condition than the normal potty training problems.

comment How many plane flights per year are considered unhealthy for a toddler?
The exposure due to cosmic radiation is actually about two chest X-ray images per flight, or 40 uSv (xkcd.com/radiation), depending on flight height and latitude. At 1000 flights, there would be definitely apparent effects (epa.gov/rpdweb00/understand/health_effects.html), known as 'deterministic effects' because they can be traced directly to radiation. So unless the OP is flying in the 100s of hours per year, they should be OK-- but he did ask for how many flights would be unhealthy, not if it's a concern :)

comment Should I make a particular effort to present great women of history to my daughter?
@DaveClarke-- the only Pixar heroine I can think of as being 'good' is Jesse from Toy Story 2. Cars, nope. Finding Nemo-- well, she's an amnesiac, so probably nope. Brave-- maybe, haven't seen it yet. Tangled-- I actually really like Rapunzel in this one. The point is, Disney's getting better, I think, but the classic stuff has no place in my house, for either my son or daughter.

comment Should I make a particular effort to present great women of history to my daughter?
@TorbenGundtofte-Bruun-- I really, really disagree. I'd argue that many of Disney's role modeling has lead to some extremely poor expectations. Snow White just waits until she's awoken by a prince, and then marriage is a breeze. Ariel can only find a man if she's mute. Cinderella waits until her prince rescues her. Nicki Minaj (arguable if she's a good role model) dismissed another one with "I am not Jasmine, I am a Aladdin"-- Jasmine is definitely the weaker, although better than the others. More recent movies are better, but classic Disney is terrible for gender roles.

comment Two year old afraid to go on potty
@Treb-- it seems that you and I are anecdotally faster than the average. I've talked to a number of physicians about this, and they say that so long as the kid is using the toilet by the age of 5, they are considered 'normal.' So maybe we're just one side of the average of 22-30 months. Also, note that there's a distinction between 'used a potty for the first time' (which our son did around 18 months) and 'uses it on their own with no prompting and doesn't wet the bed' (takes a bit longer).

Ah, so the tooth wasn't black, the gum near/over the tooth was black. Slightly different problem :)

comment When should I allow a child to swear?
@BillyNair-- if your swearing shows little creativity, maybe it's time to put a bit more thought into it :) Besides, I think you'll find that that meme your propagating has more to do with English social attitudes than anything else (viz homes.chass.utoronto.ca/~cpercy/courses/6362-ParkerErin.htm) I've seen some marvelously creative swearing in my time, and would hate to think that such performance art should be removed because it may not be 'necessary to survive.'

comment how young is too young to diagnose ADD
Can you point to any of this research? I'd be interested in reading it. The research I've found has no correlation between sugar and behavior: skeptics.stackexchange.com/questions/1435/… The correlation you're describing between blood glucose level and 'spazzing' sounds like a different approach than what was taken in that study; are there other explanations?

comment new tooth has a black color (baby 8mo old)
Well, according to that article, "Excessive fluoride. Too much fluoride (fluorosis) may cause bright white spots or streaks on the teeth." Maybe there's iron in that Vitamin D supplement? I seem to recall our boy had those two combined. It might also be time to talk to someone not on the internet :)

comment When should I allow a child to swear?
I agree with this answer. I think it's going to vary from household to household, and from situation to situation. I saw lots of kids who thought swearing was awesome because their parents were so restrictive about it, and other kids who didn't care because their parents didn't care. I'm in the second camp; I don't want it to become awesome by taboo.

comment How do you teach morals and values in non-religious households?
Agreed. Especially since there are so many different ideas about what the phrase 'good morals' even means.

comment What are the differences between a child who was born vaginally versus via caesarean section?
Don't forget that C-sections can also mean that the baby's head isn't mashed by passage through the birth canal, that the mother has much lower risk of episiotomy, and it can save the life of the mother and/or baby in the event of a problematic birth.

comment How does one formally educate a gifted child without wrecking childhood?
@HedgeMage-- that was not the case for me when I was a kid. I'd think that either gifted education varies from state to state, or has changed since then, but I definitely remember jumping around in the gifted class to the teacher reading Jabberwocky. Definitely not rote learning.

comment How to mitigate the impact of other people comparing my children to each other?
I think one of the problems with being a dad of a newborn is that my three jokes are the same ones I had from before she was born. At least, I think they are. I'm not sure. So I'll just reuse them for the next twenty years until my kids tell me to quit it :)

comment How can I make my travel schedule easier on my 5-year old?
Are you sure that his violence is linked to your leaving? What if you took a week's vacation and stayed home-- do you think that the violence would cease or greatly diminish?

comment Microwaving supper for the children in a filthy microwave
Or better yet, don't use a microwave, use an oven. Microwaves can cause hot spots in food (colorado.edu/physics/2000/microwaves/hotspots.html) leading to burned tongues and mouths. I don't know about the chemical threat, but I hate burning the roof of my mouth.
