Sura.. Are you Spanish??

You've answered yourself really.. it IS about the new baby!! clean it up.. Hug him and tell him you are so proud of him being a big boy and not needing nappies like the baby. Could you let him choose some cool new underpants??

yes i am .
thank you for advice . so this is wrong to make him feel im really upset and frustrated of him . i think this make things worse
yeas i brought him some new pants (Tomas ) his favoured to encourage him not to let it being dirty this is work for 2 days and he returned to the same thing

Yes.. Don't let him see you are upset with him... Hard, I know!
