Kerrie, it could be just a case of Kat being in too much of a hurry all of the time and not watching where it is she is going. Tehya quite often does that or will be too busy looking around and walk straight into a wall knocking herself flat back on her bum.

Does she see you if you are to the side of her and wave or something like that ?? If not then maybe you do need to get her eyes checked. Optometrists (sp) are used to dealing with kids too so I'm sure they will manage ok with her.

Hope it's not anything for you to worry about though
