My DS is 4 months old and has his first little cough and cold. We are due to go to a sling library tomorrow but not sure I should take him when he is unwell. He is ok in himself but there are going to be other babies that may catch his cold. I genuinely don't know, part of me thinks I'm being selfish because I've waited 3 weeks for this sling library so really want to go but shouldn't and the other part thinks babies get colds a lot in the first year and to just go. Wwyd?
