I have mobility issues as well. From my own experience of the mobility issue and having a teen, I can say that it’s helpful to ask her for a list of birthday suggestions. If she doesn’t put a Coach purse in there, you could ask her outright if it’s something she’d be interested in. At her age, there’s nothing wrong with asking her. She’s old enough to understand the need for a list. I also use Amazon often to do my gift shopping.😊
