I will still sometimes ask my middle son (third grade) to hold my hand if the parking lot is busy, it's rainy or dark.
He cannot be seen behind many cars, as he is short.
Usually he does not take my hand, but I do sometimes ask him to. I like having LO, as it's an excuse to have him take LO's other hand. So, he's not being the little kid, he's "helping" me by taking LO's other hand.
