Only seemed to last a few seconds but tonight ds freaked me out a little by asking 'Where's the other mummy gone?' - I'd gone into his room and just closed the curtains better as he'd been calling out that they weren't closed properly. He was looking around in a bemused way and said 'Two mummies!' a couple of times - I turned the light on and noticed he looked a bit cross-eyed. But then I got him to touch the top of my finger in front of his face which he did with no problem and counted his toys etc... He's never had any vision problems before.
Do you think he's just learned to go cross-eyed (he thought it was pretty funny seeing two of me) or is this something I should worry about?
