I don't know, I think I can relate to the crying. I think I gained a whole metric ton of empathy since having kids and get weepy at the silliest things sometimes where nothing ever phased me before I had kids :)
I know exactly what you mean. Having kids changes everything.
Dont get me wrong, I can relate to the crying but I feel that this is the physical reaction while the focus shall be more on the emotional side.
If emotions were water and I was a faucet my first child turned me from a well working plumbing fixture into a slowly leaking one with occasional gushes of H20.
She often drives me crazy now that she's older which in turn leads me to spending most nights chiding myself at my lack of appreciation for her in the moment.
