Would someone please tell me how to comfort this child?

So as another way to make a little extra income, I am helping out with the local MOPS (Mothers of Preschoolers) group at my church doing childcare twice a month. I am working in the room with the 12-18 month old children. This is a pretty fun age because everything is so new to them and they are still snuggly.

They also have extreme separation anxiety.

Seriously, I had forgotten about this phase and how traumatic it can be. The look on their little faces as mom hands them off and waves good-bye is just heartbreaking. Today was our second meeting. Most of the mom's learned from the last meeting's experience and brought some comfort items for their children - a stuffed animal, a blanket, a favorite snack, etc. But there was one mom who was not here the last time so this was the first time she was dropping her child off. As she's handing the child to me she tells me, "Oh, she just has shots so she's pretty cranky and she's cutting like five teeth and it's her nap time. I'll give her some Tylenol." Then hands me the child and leaves. Can I just tell you what a MESS this poor little person was for two and a half hours??

So when the mom came to pick her up, I told her how upset her child had been and how we tried rocking her, pushing her in the stroller, playing on the floor with her and the woman just nodded and left. Um...HELLO??? A hint or two on what we can do to lesson your child's trauma would have been nice! I mean SERIOUSLY??

I help clean up the room and I walk out to the lobby and stop to speak to another mom from my group of kids and this same rude woman just comes over and pulls the mom I'm speaking to away! I mean, physically grabbed her by the arm and pulled her away! Honestly, I'm ready to slap this woman! So basically, not only is she seemingly unconcerned about her child, she clearly is just a selfish individual all around.

Charming.
