Maybe she didn't cry because of the toy but because of the terrible food you fed her.. Are y'all serious?? You fed a one year old McDonald's and you're proud of that?? I'm sorry but most adults don't feel great after eating fast food, and if this was one of her first times trying it out, she could have just felt really bad because of a reaction to the food. And now when she see's that toy she's wondering if that bad feeling is going to come back... Please, I can't tell you how to parent your kid but you are asking for some advice, and mine would be to not let her eat that crap there is nothing good or beneficial for her in it. If anything you could be well on your way to giving her some sever problems later. I've never seen a kid eat any kind of fast food or junk food and behave well or not get sick afterwards.. This food can cause all kinds of problems from ADHD, Depression, Diabetes and the worst Cancer. If you love her with all your heart you'd keep this kind of food out of her life so you don't have to risk these sever problems later.
