DD is nearly 16 months and is our first, so we don't know what we are doing in some respects. She has been walking for a few months and can now run too (obviously not very fast). She won't hold hands when walking and doesn't seem keen to go on reins. She really just wants to go where ever she fancies. Does hand holding come later? Or are some children hand holders and others not? Is there anything we can do (other than the obvious praising when she does it) to get her to hold hands?
