What is best for my Kids?

Have you ever just wanted to be able to know what is best for your kids... I do everyday.
I am creating this blog to give other parents information about products or ideas that I have found to be helpful, hurtful or confusing to me. My hope is that with some positive posts, together we can figure out this whole parenting thing and do what is best for our kids!
Let me start with the whole Cold Medicine debate... I have been focusing on this issue because my children have all been fighting colds. I have 3 children ages 9 1/2 , 6 1/2 and 2 1/2 years old
When my first child was born and she got sick the doctor would recommend cold medicine to give her; but now everyone says that cold Medicine shouldn't be given to children. How do we know what the best choices for our children are. I took my Middle child to the Doctor yesterday and he told me to just use saline drops to clear her nose and to just give her a antihistamine product before bed. I have been told this in the past and used it with my son who is the 2 year old and it seems to work well. Anyway I tried it last night with her because the night before I had given her one of those over the counter cough medicines that is supposed to work for 12 hours and it didn't work at all.. the poor thing still coughed all night. What is the deal with all of this information and how do we know what the best choices are... anyone out there have any input I would love to hear from you.. Lets help each other do what is best for our kids! I look forward to hearing from you. Rhonda
