DS is fully toilet trained in day but still in pull ups at night. He has the Huggies pull ups night time pants which I usually order as part of online shop and they have a cars theme. However today he was with me when we popped in to shop to stock up. They had two types - our usual cars themed "boys" or sleeping beauty "girls" He saw the sleeping beauty ones and wanted those, I tried to direct him to his usual but he was having none of it. I didn't want to have to say these are only for girls. We ended up getting one of each as they were on a 2 for something offer but what I'm wondering now is there actually any difference between "boys" and "girls" pull ups or is it just a stereotypical branding thing to appeal to kids? More than happy to put a boy in a pink pull up but don't want it to cause a wet bed if they are designed differently.
