I make dinner and serve my 2 & 1/2yo's on her own plate yet she insists on coming to my plate and eating off that instead. tempted to just put it all on my plate and let her come and get some but then when she gets to kinder age she might not eat there cause of it or she might go and eat off some other kids plate. Any tips?
