I have a 10 month old DD who I take to playgroup, normally she's fine playing with other kids and she has learned to share the toys there, and when an older kid comes to try to take a toy she's playing with she's pretty good at keeping the toys and the other moms are good at telling their kids to not take babies toys, and I tell her to share, so I don't mind, but yesterday she was trying to walk pushing a car (she just started cruising) so I was a bit careful with her and this older kid (around 3) came and tried to take the car off her, as I said normally I wouldn't mind but she was using it for support and the mom was just chating and just looked and continued on her chat, so I just had to put my hand on the car to make sure she keept it
I know it's not the kids fault, but I felt a bit rotten at not letting him play, but also I didn't wanted to take her off it so he could play, and I'm a bit angry that his mom didn't even pretened to tell him not to
