My 2 cents is this is for attention and asserting herself. Don't go through pair after pair of jammies or underwear. Pick your day, and then put limits on it. Tell her she can pick her jammies out of her drawer for bed. If she doesn't like them and wants to go nude, let her. Who cares? She'll either get cold, or see you don't care and then put them on anyhow. The other day my daughter did NOT want to put her shoes on, and we were about to go walk on a large gravel driveway. I explained to her, etc. I said, okay, no shoes and set her down on the gravel and went about unpacking the car. 20 seconds later she said, "ouch, mommy, shoes." I said, "oh, you want your shoes. I think that is a great idea you have because the gravel is very ouchy on our feet. Okay, mommy will get your shoes." Her comfort will win out in the end! Don't let her play you and dad either. If she pees her bed, she is the one who has to clean it up, and herself. Let her call the shots and when she makes a decision you know is good for her, praise her on what a good choice it is. But, I really think the only way you're going to get through this is to limit things for her. Maybe because of the separation with you and dad, she needs to feel what her boundaries are in the home again to feel safe? Also, some kids are more touchy than others, and this can come out by saying clothes hurt. Look up spirited or touchy toddler on google. My daughter does that too sometimes when she's in a frustrated mood. Suddenly the cuff of her sleeve is painful. So, I just play around with it and say, "ok all better." For now that appeases her. Anyhow, good luck!!! Hang in there!!
