What's making you cry?

Kat • Happy mother to first child on 7/7/15.
Just curious what brings all you mamas to tears? I haven't been more emotional than my usual self until 10 wks and now I cry at everything. Kindness, sadness, happiness, smiling, music... Going to see Trans Siberian Orchestra in a couple weeks and am afraid I'll be a blubbering fool. So, ladies, what makes you cry??
