Big Sisters, Anatomy lessons

My granddaughter, Mykenzie, has apparently been following in her mother’s footsteps lately. When her mother was able to walk, before she was even able to talk, she began mothering her brother, even though he was the older sibling. It was sometimes subtle, sometimes not. As obvious as handing him his Sippy cup as she was getting hers or passing him a chip from her plate when he ran out of his own.
As subtle as watching him as he fussed over one thing or another – and he often fussed – and moving closer to him to see if that would soothe him, all the while carrying her ”blankie” in her clutched in right hand, index finger folded in her mouth. They would often fall asleep that way.
Now her daughter (three years old) has taken up the torch of being cheerleader and champion of her younger brother (two years old). From encouraging him to sit still for his haircut, an experience he does not enjoy, to climbing into his baby bed – side rails up – to fetch his pacifier; which both of them know he uses only at night.
When their mother saw the two of them walk out of Grant’s room with him contentedly sucking his “paci” it did not take her long to put the pieces together. "But Mommy" she explained quickly, "he said 'Please.'" I am not sure I have the heart to tell her there is so much more yet to come. If at this age the two of them are in cahoots on this kind of mischief, what will she and her husband be up against in the years to come? I think it may be fun to watch from a grandparent’s point of view.
I want to be careful how I say this, but my daughter tells me Mykenzie is very inquisitive about anatomy. Being in the presence of a dozen nursing mother’s – hers being one – has made it difficult for her to understand why her upper body anatomy and that of her younger brother is so similar while the corresponding anatomy of the mothers and fathers she knows are so very different. What troubles her most is that boys are allowed to run around without a stitch of clothing above the waist and little girls must keep their upper bodies covered – when essentially there is no difference in the form at her age.
Well, I’ll let her mother and Grammy handle that discussion.
