My son is 2 years 9 months, recently i have noticed that he likes to undress himself until he has no clothes, and i let him do that as long as he is indorrs. So last night i was doing ironing, so he goes and climbs on top of my white clothes, i have been saying no for a while so i decide to smack him bum, then he says i am going to wee wee on you, i ignore him, and he really weed on my legs, what's gotten to my boy, still a few minutes later i say no to something then he goes and wee on my mat. i don't know where this is coming from, i was just not sure what to say to him, i was speechless.
