My son was a super fussy baby. He had colic, reflux and gas that he battled until he was about 6 months old. He cried every single evening from 4-9 for the first 4 months of his life. I couldn't take him anywhere because he screamed in the car, and would cry once we got there anyway. Around the time we got all that under control, he had ear infections for another 5 months straight! He's been a pretty terrible napper at various parts of his life, and didn't sleep through the night really until he was 13 and 1/2 months old. Ahhhh! I feel your pain!!! I feel sad that you've ruled out other children because she's difficult. I wouldn't do anything permanent just yet. It seemed that with each month he got a little better. 5 months was a turning point for him for sure! I remember being with a group of friends from church, and he wasn't crying (for the first time!). One friend came up to him and said "you're really turning a new leaf today aren't you?" As he became more aware and was able to do more for himself, he got happier. I will say one thing -- that foods can really mess with a child, and not all pediatricians believe that. My son is terribly, horribly cranky with dairy of any kind. Fusses non-stop, but that's really his only symptom. He's never tested allergic to it, it just really makes him unbearable to live with. When I was nursing I couldn't touch any of it. Not even baked in bread. And now at 19 months I've also had to take away oatmeal, which also puts him in an extremely foul mood. And for that matter, makes him incredibly ornry and naughty! If you're nursing, it's worth a try. He was a completely different baby once I started messing with my diet. The pediatricians even saw the difference! Other than that, one of these days she'll surprise you and you'll find that you're not just making it through the day, but enjoying being with her! Hang in there mama! Every day is a new day!
