Every time my toddler gets a mild infection (e.g. hand-foot-and-mouth, roseola), I have the same dilemma: Do I tell his friends' parents?
On the one hand, it pre-warns them of symptoms to look out for, means they don't panic and don't have to repeat my research. On the other hand, I feel it means I have to stay locked in for weeks or be Public Enemy #1. But if I don't tell them, don't stay away, and their child gets very ill with it, I will not be able to forgive myself.
I put myself in the position of other mums. My son doesn't suffer too badly with illnesses so I am OK with exposing him to others - for me it is a fact of life, and the good (immune system building) outweighs the awful (seeing him suffer). But I realise others are not so lucky and some children gets everything going and/or get extra poorly from things.
What are your thoughts?
