Anyone else’s toddler seem afraid of men out of no where?? My daughter seems to cry at times if a man comes to greet her or too close to her at church now, because that’s where she has the most interaction with men. And she gets so fearful, it shows on her face. She does it with my dad as well now, but I was thinking it was because she doesn’t see him much. I’ve been told that it may be because they’re really tall to her. She’s rarely ever out of my sight and I’m never really around men unless I’m at church. So could that be the issue? Or is this a normal phase of some kind?
