My son is 5 months old now, and my wife is vegetarian (not vegan, quite a difference)...she eats fish, most sea food, and eggs
at first I was pretty worried about her not getting proper nutrients while pregnant but it didn't take long for that worry to go away.
my son is in the 100th percentile in height ...got Dirk Jr over here...also above average weight (obviously at that height) and he is not an overweight baby.
he is also well advanced in terms of focusing and eye movement...eye contact etc
there is basically no chance of autism in my son because he has shown so much focus which is something I was very scared of at first...because autism numbers are through the roof right now and no one knows why (I suspect prescription drugs)
Discipline should be the last resort; teaching should be the first. If you teach your kid well with enough incentive to motivate him to keep on doing what he is doing, then there should be no need for discipline since he will be incline to do it anyway. There should be a distinction between positive discipline and negative discipline. You can't just beat the living hell out of your kid and expect him to know what is right or wrong, you have to teach him and then encourage him to keep on doing what is right. Discipline is just an easy cop out and not true parenting (this is hard for many people to accept as true). You got to teach if you want them to learn. Beating and punishment should be the last resort, not the first. If you fail as a teacher, then of course, you will have to discipline the child, but it is your failure that is the cause of the discipline, not the child's inability to learn. Big difference. Many parents today fail to take responsibility for the failure of their kids.
I think you're confusing the definition of discipline with punishment. Yes, you as a parent set the example but you also set the boundaries on what is and isn't acceptable behavior.
Having a kid has made me much more appreciative of my parents and what they went through to raise me. You are right in that you always want to be nurturing and positive but sometimes "because I said so" is a perfectly acceptable explanation.
