He was sitting playing in the lounge when he fell sideways onto DS1's train track. Poor thing has a red mark on his head and a raised line where his head hit the plastic track.
I've put a cold compress on it for a few minutes, now he's feeding.
Still seems alert and happy.
Is there any need to call nhs direct or get him looked at? I'm going to keep a close eye on him for a bit to see how he gets on over the next few hrs.
