Hi moms, I’m a 32yo FTM. My LO is 22 months and this morning I took her to a children’s play place. We go here often. My child knows and loves this place. About an hour into being there and playing, another child grabs my little one’s hand and just starts pulling her with all this child’s strength. The child did look older than my child, by how much I’m unsure. Maybe a year or 1.5-2 years older than my child. The child’s caregiver was within reaching distance. I was sat across the room when it happened but quickly ran over and ungripped the child’s hand from my child’s arm and removed my child from that environment. For context I always keep my child within eye shot even if I’m sitting across the room (it’s a small room). My child was hysterically for a moment after it happened and I of course I asked if she was ok, checked that her wrist and arm hadn’t been pulled out of the sockets and hugged her. My child took a couple minutes to calm down but wasn’t feeling very safe any longer. I gave it 5 or so minutes while I monitored my daughter, she played again but the same child that pulled her arm came over and aggressively ripped the toy my daughter was playing with from her hand. My daughter became upset again. And I decided it was time to go. My child is fine of course. These things will happen, I understand this. I did hear the caregiver say that wasn’t nice to that child after I removed my daughter from the situation but I was not pleased with this caregiver for not intervening faster while sitting right there and have the child she was caring for (unsure if it was the mom or grandma) ungrip my daughters arm. I’m the kind of mom who at this same place there was a child acting out and stepping on coffee tables meant for parents and I said hey little one that’s not safe and picked them up and redirected elsewhere. The mom was around just I was closer. I would have appreciated the same from other moms or caregivers and my mama heart is sad that my daughter didn’t get the same kind of kindness. My question is, what do other moms do in these situations or similar situations?
