How can I stop dd "bumping" into people?

[BlossomHill]

Dd (who will be 5 in 2 weeks) has a language disorder and obviously this effects different things in her life.

We have just come back from holiday and dd spent most of our days out bumping into people. The thing is it wasn't on purpose. She doesn't seem to either concentrate enough (she is slightly hyperactive/attention problems) and seems shocked everytime that it happens.
Another example is if say we were on the beach and she was in the sea she would run across peoples towels, practically over them and soemtimes into them to get to us. Again not realising that she is going to bump into them!
She does have slight motor skill problems, such as writing. Although her writing has improved since starting in reception in January.
I was wondering if we should ask to be referred to an Occupational Therapist? Not sure if this is the right way to try and help dd? Any suggestions gratefully received!
BTW We did manage to have a peaceful and stressless holiday

BlossomHill, I've had some tips from my SIL, although my youngest son's a bit younger than hers (her son is your son's age). She recommends role playing games and if he's verbal enough, "what if" games.

So maybe put down a towel and teach her to run around it, etc. I'm not really sure how to teach personal space. We're having trouble with that with my eldest son also, but in a "he's socially graceless" way. I'm going to talk to her soon.. she's really helpful!

I know there's more to it than the simple "teach her otherwise". But if you'd like more info (I know there's more info!), let me know. It's a part of her son's therapy and she's really happy to share it. I just haven't encountered the complicated bits yet (my youngest son has a language disorder, also, so he's a bit behind and not up to it).

Could it be something to do with depth perception? (I think that's what it's called anyway!) It may be that dd thinks these people/towels etc are further away than they actually are. I'm not sure what the solution is though so that's probably not a lot of help to you!

Forgot to add that I'm glad you had such a good holiday.

Thanks Coppertop! It was one of the most relaxing holidays we have had since dd has been born. Dd has calmed down so much since last year. All of the other holidays we have had have been us chasing her around and watching her like a hawk so it was a refreshing change to actually stand back and watch her and ds enjoy themselves
JJ - I didn't realise your ds had a language disorder! I thought that apart from Eulalia and Jimjams dd was the only one on mumsnet!
I would still be interested to hear about OT's though as it may be of use to dd. Any thoughts welcomed!

Any more advice, please????

Anyone?
Would really be interested in hearing about OT's as I don't know too much!
