Mums withs 2 or more

How do you do naps?? I'm ok with the mid afternoon one as my 2 year old and 2 month old have that one at the same time but the morning and late afternoon naps for my lo are sucking lately!!! I set my 2 year old up with activities or a DVD while I go put his brother down but sometimes it takes ages to settle him and by the time he is finally asleep my DS is back to being loud again and then my lo wakes or I'm just constantly shushing my DS and I feel bad. Heeeeeeelp meeeeeee!!!!!
