I second the older child trick. My DS (almost 5 now) was extreemly high need as a baby....well, for about 2 years. Now with DD (13 mos) he dances and sings for her.....reads her books, all kinds of entertaining things. I always say that I wish I would have had one of him for him! She is a very happy and easy baby but he is sure nice to have around when she is fussy. So I think the suggestion to have over older kids for playdates is a fantastic idea.....good one
And good luck to you. With all of the attention in the world (SAHM, 1st baby, freshly moved away from family so ALL of my attnetion was focused on DS) DS still cried a lot. The best advice I got from a caring lactation consultant was, you can't always make them stop crying, you can just be there for them while they are going through it. Remember that when they are having a hard time, you are right there for them and if their needs are more than your two hands can provide at the moment, they are still going to have better lives because you are there and caring about their crying. It gets easier!!
