so my 4 year is fully potty trained. hasnt wet the bed even in a long time. he has pretty much always acted weird when he first wake up from a nap. like hes zoned out and just completely confused. off in lala land. but still he never had a problem getting up and going to the bathroom to go potty. well yesterday he got up from his nap crying. holding himself. i asked him if hes okay and he said yes. so i told him to go potty. got up out of my chair to follow him in there. but he didnt go there. instead he went into the kitchen right up to the tall garbage can and peed all over the side of it. he has never done anything like that before. crys when he thinks he not gonna make it to the bathroom. should i be worried about this? maybe should i take him to the doctor? i dont know what to make of this. i couldnt believe he did that. watching him my jaw litterally dropped. what do you think?
