Most kids seem to socialize by playing running games. Catch, tag, etc and if she refuses to join in any running games I worry about her being able to make and keep friends. I doubt there are many kids around of her age that would rather sit and chat (As she likes to do) than run around, jump, do something active.
She joined a new school in September (year 1) and seemed to be making friends last term but now the kids seem to mostly play running games so she has stopped playing with them. In the morning before school she just awkwardly stands around in the playground.
I think it's not so much that she doesn't like running but that she feels very conscious that she is much slower than the other kids. She is quite a bit smaller and probably weaker than her classmates (end of August born and very poor eater). We've had her thoroughly checked out for her poor weight gain and she is fine.
Not sure what to do about this one. Not only is it good for her to be more active but I also don't want her to lose her friends or be isolated from her class mates or be the odd one out.
