DD has a bit of a cold. She didn't eat any supper last night (apart from a bit of yoghurt), slept for 15 hours which is very uncharacteristic (usually it's about 11) and now hasn't had any breakfast this morning. She did have milk before bed and first thing this morning. She looks knackered and keeps lying down on the floor in an exhausted way.
Is she just fighting the cold? I don't want to (can't!) force her to eat but I'm worried that she now hasn't had any proper food for 24 hours.
