I think one or two hours watching TV is enough for the kids as more that that when become habitual can harm their eyes and also the things they showing on TV these days can harm there mental development also they watch the things they shouldn't be watching. You should always keep your eyes what...
That is really great you and your family had a very great time there, specially kids gonna love it. Don't forget to take each and every thing your kids are habitual, especially for the little one. Take care and have fun.
I think you should avoid them. The much you will notice them they will make you irritate.There is a simple way to avoid them just say yes and OK every time they say something with a smile. When they will see that it is not bothering you they will stop doing that.
You don't need to worry about it at all. If you cut the hairs not they will come back and will be much better and thicker that the previous ones. And they will be in better color than now also.
