We will be going in Sept with our DD5 and DS almost 3. DD has been twice and is very good at staying very close to us and being very attentive. It will be DS first trip. He, on the other hand, likes to take his time and look at everything around him. He also doesn't seem concerned if we're out of his eyesight (I tested him a couple of times by intentionally moving away from him while keeping him in sight and he didn't seem concerned at all). We'll have strollers for both of them and are very good at keeping them very close to us. However, in a big park, I want to have a back up plan in case one of them gets lost. What are some quick ways of putting IDs on their clothes? Do people put a piece of masking tape on inside of bottom of shirt etc.? Would you put your name and hotel phone number, or their name? Any help appreciated. Thanks, Jo
