DS1 started doing much the same about 3months after DS2 arrived. He'd just stand in the middle of the room and take wizz on the carpet. Pretty annoying isn't it?! I just ignored it (most of the time) as it was obvious he was just trying to get my attention, letting me know that I was spending too much time on DS2. It does pass honest. The times I couldn't ignore it (hormonal moments etc) I tried to ever so nicely explain that he really shouldn't be doing that as he's been such a clever boy using the toilet all by himself......took about 6/7weeks to sort it. Then we got the carpet cleaned to get rid of the niff
