Potty training

NA

My son has finally got the concept of him peeing in the potty.

My question for mummy's who have successfully potty trained is did you use diapers or pull ups when you went out? We currently use potty training underwear. He will normally say "I pee" to let me know. He is normally home so no issues at all. Tomorrow we will be going out for about 3hours and im not sure what to do.

Any advice?
