I guess babies get different types of colds just like adults. I know when Alyssa had her first one there were no coughs but a constantly runny and blocked nose. We held off going to the doc cause we didn't want to seem like paranoid parents, but we finally did when her temp was high and she wouldn't keep the pamol down. The doc told us we should go in as soon as we suspect a cold just cause it's free anyway and better to treat early than when their fever is high cause it's worse then..
Hope Elle is feeling better soon
