Well, i dont have a kid yet, but still i felt i can help u answering this one. :) Kids always demant attention, so its very normal what ur elder child is going through. Try encouraging him more in doing things independently by telling him that he/she is a grown up now and also at the same time try n inculcate feeling of love inside him/her for his sibling by giving your adult child some more responsibilities...... like helping u out wen u r handelling your younger child. that will make the adult child feel lil more important and ADULT!. try it, its just an advise. :)
