Our little one is in a new preschool - smallish center that's in between home daycare and professional preschool. There are about 6 teachers each with a small class of students of their own. A few times a week the teachers swap classes for short periods - due to circumstances or pool their students together because some teacher has prep work or personal work. We are working on a hand-written note by me and a drawing (with help) by kid for each of the teachers. I would like to add a gift card for each of the teachers. Please suggest amounts (or ranges) for primary teacher and other teachers in school. I wouldn't want to overdo/underdo it and make these new "relationships" uncomfortable/inappropriate in anyway. Also any suggestions on which gift card to go for: Amazon/Starbucks/Target/Michaels or any other place? Note: I do like the teachers a lot - they are warm, friendly and greet us with a smile every morning. They do a good job of taking care of the kids.
