Wearing diapers in public can feel scary for your partner at first but it’s all in their head. As long as they wear the right clothing the likelihood of someone noticing is near zero. The fear of being caught is very valuable for your DD dynamic though which is why public wearing is important.
Almost all DD rules include the wearing and use of diapers in public. Initially, this will often be just for wetting but it should expand to a full toilet ban in public as quickly as you can manage.
Getting used to wearing in public is just a matter of practice so get started straight away. Initially make sure to use thinner medical diapers, put them in a plain colored onesie and make sure their clothes are baggy enough to accommodate the diaper. Dark jeans work well and dresses or long skirts are ideal for baby girls.
Getting them used to wetting and being wet in public is the next step and can be achieved through longer times away from home giving them no choice but to use their diaper. A great DD day trip for this is a visit to a zoo!
Over time use thicker diapers as both your confidence builds to make sure they’re always aware they’re in diapers.
As soon as possible you’ll want to remove the ability to use a toilet in public which might have been allowed for #2’s. This key step makes things easier as taking off adult diapers temporarily to use a toilet is challenging. Thicker adult diapers can avoid the need for public changes for shorter trips and don’t be afraid to make them spend up to 2 hours in a filled diaper, that is what they’re for.
For day trips where a diaper change is likely required you can use a handicapped bathroom to change them, allow them to change themselves in a standard cubicle, or change them in the back of your car.
