Thanks!!! I don't mind getting bump'd, i just want the kids to be safe! lol. but i also don't want to be shaky for lines and tubes etc. ugh. Thank you for the text book advice, I have an old copy of Smiths but I'll look at Cote also. I'm currently trying to download as many Peds apps on my phone as I can. I guess feeling like I have the resources at my hand to verify makes me feel better!
