I feel like a total Grinch saying this, but as a teacher, I and most teachers I know can be pretty suspect about homemade foods. I will always take them and say thank you, but often they end up in the trash. There's just a sanitary and unknown issue that makes me wary.
I couldn't agree with this more! I've worked in Preschool for 6 years and have never eaten a homemade gift. It's nothing personal, I love the kiddos I work with & truly appreciate the thought. But I also spend my day telling your child to get his/her hand out of his/her nose, mouth, or pants. It can't hit the trash soon enough when he/she tells me they helped you make it!
