<human>: Give me a shortened version of the text

So, I work with a lot of people aged 17-30, so gossiping and immaturity is expected, but this has actually brought me to tears at work and at home. People will be dicks, I know.

I am 27 years old and I confided to one co-worker after her persistent questioning about my life that I couldn't conceive naturally, no biggy to me, however she made a huge deal about it asking why I didn't adopt, why haven't I had fertility treatments. She is about 18 years old, I shrugged it off to social immaturity. 

However, on that exact same day, she started making comments when I would smile or talk to children (I work with a lot of children and families), or if I mentioned "that was a cute kid", that I was being creepy. She even said it sounded like I wanted to kidnap the child.

I actually almost burst into tears. I was stunned so didn't know what to say, so just chuckled that it wasn't in a creepy way. Ever since then she stares at me when I speak to mothers with babies or children. She makes these remarks often, and each time I feel so angry. Another co-worker has also started saying this to me. 

I am just so hurt by this, I doubted myself at first and thought I actually was doing something creepy at first, and stopped smiling at children, looking at them, or speaking to them. I feel sad, but I know that I am not wrong for being joyful around children. I do not laugh at them, or directly seek them out to talk to them, they come up to me. Everything was fine before I told her this.

Is this how men feel around young children? I feel stigmatized. How on earth do I handle this? She is a good worker, and a good person, just on this I have no idea what on earth to say to her to stop it without sounding defensive.
<bot>: What do I say to a co-worker who automatically thinks I'm a creepy kidnapper because I can't have kids?*
