iggy's mood swing

we've been noticing that iggy is showing some jealousy.. but thank god he didn't bully adik.. he'll flip over nothing.. cry over everything.. even though we didn't scold him.. We think that he sees our affection towards adik is more and thought that we don't love him.. that's why when I sorta scold him, he'll run to his room and cry.. then he would ask me to kiss him.. "dada tak cium... huhuhuhuh.." I guess that's normal for a 4 yr old.. tapi yg tak bestnya.. 3 nites in a row he had wet his bed.. any tips on that?

note to self.. take more pictures of my 2 sons daily.. heheh
