Dh wants to get safety harnesses for our 18 month DD twins. I don't like the kind that go over the torso, but I can live with the wrist kind. Before I make a trip to Wal-Mart, I'd like to know if anyone has seen them for sale there. Target is 1 hour 15 minutes away, but we have some appointments near it next week. I hate shopping so I don't feel like just going in to check. TIA!
