It’s a good idea to show your toddler the bathroom when you arrive at your destination. That way, they will know that when they have to go, there is a place to do that. It will also help make that first potty trip less scary.
When your toddler needs to use a public toilet, make sure it is clean. Always accompany them into a public restroom. Many places have family restrooms that make it easier for a mum to take her son or a dad to take his daughter.
Of course, there are things you can try to do to help avoid public toilets as well. Make sure to have your toddler sit on the potty before leaving home. If your child still goes between nappies and underwear, you may want to use a nappy when you are going out.
