DD is also 5. It may just be her, but I don't think at that age children take any interest in what's going on in the lives of others. I ask about some of her friends and she doesn't even know where they live, how many siblings etc!
I'm not sure if she thinks all children go for OT etc and we haven't discussed it as anything other than that she does it to help her grow big/strong etc. She enjoys the sessions esp soft play/'assault' course. She doesn't seem to have any complex about going for therapy at this age (she has low muscle tone and it may be another issue with your child - total lay person here!).
However, DD was first referred to physio as a baby so has been going off and on for as long as she can remember. She was showing no signs of crawling/walking so needed some help to develop core strength. Now she does exercises about 3x per week for a few minutes to strengthen her (she has low muscle tone).
I made the decision to ask for OT about the time she started primary school because I could see how difficult she was finding dressing and anticipated writing, using scissors etc could be tricky. OT helps with strengthening shoulders (to feed into fine motor skills e.g. writing) and gave us exercises inc. kneading, cutting, pegging to help to strengthen hands and with coordination.
Of course, you would need to get professional advice for your own child's needs.
I think she has really improved over the last 6 months - year, though we do have off days if tired etc. We await a further assessment to see if she is still 'developmentally delayed'.
When I see her in the park there's no doubt most of the other children of her age are more physically able, but its not the total nightmare it was a year or so ago. She can now participate. We found if we took her to emptyish play areas she would give it a go, but when other kids were about she would freak out (self conscious at times). But we can now safely go to soft play birthday parties!
She has been teased (slowcoach etc) but we are persistent with the activities and she goes to dancing class (she's not the best but hasn't noticed). It does need a lot of patience though. When she started school she talked about not being able to keep up in the playground and other children knocking her over etc but seems to have come to terms with that this year. Not every child (even the boys) will be physical and she seems to have found some quieter children, at last, to play with.
I would say her handwriting is a bit messy so she uses triangular pencils (OT could maybe advise you). She still needs stabilisers on her bike and goes along slowly on her scooter.
Sorry, long!!
