It is a horrible time when our children are unwell, but as they spend so much time outside and with other kids at school, they end up being around a lot of bugs and eventually pick things up. It is inevitable and as awful as it is to see them get sick, they will recover, and it is the parent's job to help them get through it as painlessly and as comfortably as possible. There are a few things you can do to help them get through being unwell.
One of the first things is to get them comfortable, the prime place is for them to be in their bed or to make up a bed on the sofa for the day so you can keep an eye on them, and they are all snuggled up. Depending on if they have a fever or not you can get them a hot water bottle. Keep the windows open so they have fresh air.
