Ds1 who is 4 complains a lot of sore legs. This morning he was holding it going down the stairs but later on seems fine. We went to a friends and my friend mentioned he looked really pale. His sister had a birthday party yesterday and he did seem a little warm but was only 37.5 - admittedly he is usually about 36 but no temp this morning. But he's been a bit clumsy. He went to the park with his friend and they came back quickly as he hit his head on the gate. Later he walked into the handle of the patio door and later fell a few times - just really clumsy. Took him to nursery but he seemed really subdued. Think he's alright? He eats a lot of meat so can't be anaemia. Hopefully it's just a virus but he is REALLY pale.
