DD#1 just turned 2 and has been playing with diapers (clean thankfully) for a few weeks...ALL THE TIME. She wants to hold as many as she can at once and keeps asking for more. She has me put them on her stuffed animals and then goes to change their diapers because she says they peed in the diapers. She sleeps with about 10 diapers in her crib. She recently wants to wear a swim diaper over her clothes all day long, so we have to put it back on after we change her diaper. We have started having her sit on the potty more at home and at school, and I'm wondering if this is somehow related to her knowing subconsciously that she will not be wearing diapers for too much longer. Any thoughts?
