Hi K.,
I agree with Dana on this one! I'm a Chiropractor too and can tell you it is very important for your kids to have good posture. Once in a while isnt too bad but they are out of your sight enough to keep reminding them:) It will help them later in life. When you see people with hunched over backs, its not just due to weak bones but also poor muscle strength which is built upon a lifetime of constant training. However, dont confuse this with relaxing every now and then. If they are watching a movie, perhaps they want to lay down or slouch a little. 2 hrs of constant sitting up straight can be hard for anyone, especailly if they are being still. Also, being clean is great but too clean isnt. When you say your husband is compulsively clean it makes me worry. We need those 'good' germs too! They create the 'good and friendly' bacteria in our GI tract that help use fight off the sniffles and simple colds, etc. If your not exposed to this, especailly as a child, it can weaken your immune system and have a neg. impact for life. Just be cautious and let them get 'dirty' every now and then. Hope this makes sense:) You may also want to give them probiotic drinks to help build up the good stuff if this is the case. Yogurt would work too. Feel free to contact me if I can offer any more advice. Best of luck to you guys!
