    "Do you have any idea how hard it is to be a kid?"My 7-year-old daughter once asked me.My initial reaction to her complaint was eye-rolling,along with thinking,“Being a kid is hard?Are you kidding me?”as I mentally ticked off（用记号勾出）all the hard things that her mama does.

    However,as I thought about it a bit more,I realized how silly my reaction had been.Yes,as we adults look back on our childhood,being a kid seems carefree and easy and full of fun.Coloring at school!Playing games!Riding bikes! How could that be hard?So I asked my daughter why being a kid was so hard.

    Her first answer didn't surprise me."Well,because you don't have your own phone,and you can't eat in the living room."

    I asked if anything else was hard about being a kid."Someone else is the boss of you,"she replied.

    I thought some more.What else is hard about being a kid?Well,sometimes,we don't really take kids seriously.

    There are times when I've responded to my children's tears with "It's not that bad,"or"You don't need to be upset about that."Because I believe that a cancelled playdate or a lost toy is no big deal.But for little ones,it is.

    We don't intentionally ignore these opportunities for connection,but sometimes,in busy moments of parenting, we respond unskillfully.We don't take our children's view,and we miss an opportunity to practice compassion（同情心）.
