Ah Claudia, sometimes knowing a lot doesn't help hey!
Okay about the salt, I don't think you will ever get away with something being truly 'salt free' unless you make it from scratch but in all honesty who on earth has the time?! For instance I make chicken using the royco sauces or knorr etc. I know it contains salt but I never check how much because I know it will make me completely paranoid. So I try to just balance it out with lunch or tomorrows dinner being completely salt free. This is very hard since my husband has a very fast metabolism and sweats A LOT, so he needs salt. I think the thing is as with everything else in life - everything in moderation, just balance it out, but try and steer clear of adding more salt or extra salt somewhere. I am sure James will love your stews and soups!
About the omega rich foods. (I'm not a scientist, so can only tell you things from my own life) My parents grew up during very tough years so meat was a once in a month treat. They didn't live near the coast so fish (as well as chicken) was something they never had. So when they moved to SA my mother stuck to what she knew. We grew up on veg, fruit, rice, potatoes and mince - my mother can make 7 different meals a week by using just mince. As a once in a while treat (read once to twice a year if money permitted) we'd get steak, my mother hates touching meat so my father had to make it. The only fish we have ever had growing up was fishfingers, once to twice a month. Now with regards to brain development - we were all A candidates, very 'street smart' if I can call it that.
I think you really have to give yourself a break at some point. I mean if your child goes to school and doesnt get an A+, are you really going to hang your head in shame and blame yourself because he never had omega rich foods growing up? I mean come on - I'm sure somewhere (you won't even have to look very far!) you will find a couple of children who were pumped full of every necessary omega/vit etc from an early age but they still aren't A type material. I'm guessing thats possibly almost the only way to access brain development, but I can show you some very successful people in life who aren't thought of as brainy! I think a supplement would possilby be easier just to put your mind at ease.
B still hasn't started on a vitamin supplement and I'm still not sure if I'm being stupid by not having started yet. I went to the pharmacy to look at the different types and the ones I liked had sugar in them! Like HELL NO! Anyway, think about it this way, your family possibly have healthier eating habits than 60% of most of the world population!
About the dinner time. B also is in bed by 7. Hubby gets home at 5 (round about) so then I start dinner. We eat at 6 and usually start bath after 6:30 as it doesn't take 30min to eat (even on a bad day hubby can scoop his food in with lightning speed, 15min tops for dinner) so he gets time after dinner to play with B and then starts the bath bed routine. Oh yes and for this she usually napped from 1 - 3 or 2 - 4 to be able to stay awake till 7. But she dropped her morning nap recently, boohoo!
Hope that helps a tiny bit!!
