Sorry if this sounds stupid, first baby so i've no idea what i'm doing... He's got a bit of a cough, I know i probably sound like I'm being all pfb, but do i take him to dr's? Its not a bad cough,had it for a few days now, I certainly wouldn't go for myself, but should I take him as he's under 6 months? I've never taken him for anything other than 6 week check, so no idea! He's 19 weeks tomorrow. Thanks!
