To begin with you should understand that you will never be able to isolate the noise and other inconveniences to your baby. Did you do it with the first baby, but second or third this will not happen. Your older child also has the need to run, jump and play, it can not constantly be punished for it, so you their own hands to set up the older child vs the younger.
No matter what you are worried about the baby, do not forbid the older child to touch it. To get is not worth it. This close contact plays an important role in developing understanding among children. The same applies to help care for the baby. The eldest child is not obliged to help you, but if he wants to do something for your baby, do not forbid.

Even if the baby is cranky and wants to go home sometimes and will senior Chad should be taken into account. So the youngest child from infancy to learn that he is not the only one whose opinion matters.
Praise your older child, put it in an example for the younger. Especially when the youngest is a little older and begin to understand what you say.
