I know. It's just an ordeal isn't it- and it's harder, because you live them sooo much, you can't stand to see them upset, or think you are not doing it right for them. It'd be almost easier if you didn't love them.

I've heard the settle into a routine, and things get easier after 6 weeks, but do you know what? I think you just get more used to it after 6 weeks. I remember waiting and hanging out for the majic to happen at 6 weeks with my first- and nothing happened at all. She developed colic at about 4 weeks too, so she would scream non-stop for about 2 and a half hours starting at 6ish, and right through 'till about 8.30pm every single night, no matter what we did.

I was so tired, I remember seeing things!!!! Even when she did sleep, I couldn't relax, because of the tension of wondering when she'd wake, and how long I had. At night, i'd wake up even while she was sleeping soundly, becuse i'd dream that I had fallen asleep while feeding her, and was lying on her. Then I wouldn't be able to get back to sleep, because i'd lie there waiting for her to wake again.

It is a nightmare. However, it does get better, and yuo kind of forget how bad it was, (well here I am having a 2nd, so I guess you get over it)
there's a couple of things you can do that might help.
Carry her around in one of those baby slings, so you've got your hands free, but she's close to you. They like the closeness, and they like the feeling of you walking around- just "wear" her around, she'll sleep in there when she's tired, and you can sit down and have a nap knowing you won't drop her.
There is something we used to call the "four foot rule", which maen't our baby would sceam and cry if she was not at least 4 feet off the floor- if you were rocking her while standing she'd be fine, but if you edged towards a chair-even if you didn't change the rocking pattern, and tried to sit down- she'd scream bloody homicide!!!
Keep nighttime dark- don't trun on lights while you feed her, and don't talk and play ith her, only do that stuff during daylight hours- this will help her to start to tell the difference between night and day.
If all else fails get outside- take her to a playground and sit on a swing with her either in your arms, or in her carrier. This did wonders for my daughter. If she likes the swinging motion- invest in one of those baby swing things that you don't have to sit and rock. My friend rented one for her son, and that got her though some very hard weeks.
Also- but you have to be careul about this one- put her bassinette or even her car capsule- (if you have the sort that comes out of the car) on top of the washing machine and do a load- I am serious. I used to wash the same loads, like four times, just to get a couple of hours of quiet- they like it, the vibration, the sloshy noises- I don't know what it is, but it works, just make sure there is no way she can be shaken off, or slip or anything.
She may also like being pushed back and forth in her pram- even if you don't feel like walking anywhere, you can push it back and forth while you sit on the couch., eventually you'll be able to do everything around the house using alternate limbs to keep that pram in constant motion.
I used to have to bring our pram up 3 flights of stairs to do this, and then down again if I wanted to go anywhere, but, it was worth it- I could sit and watch oprah, and eat something!!!!
The main thing is, it is hard, it's very hard, but it's not just you-and, it will get better. You need to be good to youself- I gave up breastfeeding at 4 weeks, because it was just too much onm top of everything else- it didn't make that much diference to the baby, but I had a little more energy, and my husband could take the odd feed at night, or first in the morning, so I could get some sleep.
Get out whenever you can- if there is a new mother's group in your area, join, and go to every meeting. Go to everything organised for babies, and mothers, the days don't stretch out so long when you've got a plan of action, and you feel better and more human when you've been out, and talking to other people. Plus, people make a fuss of a new baby, and it's good to be reminded of how lovely she is, and how nice it is to have a little baby- even if you are only having a cup of cofffee somewhere, people are bound to dote on her, and ask you how old she is, whether she sleeps etc.
Get out there!!!

Look after yourself, if you really really feel terrible, or think you are not coping, make an appointment with your doctor, or health nurse, ask for advice, they will help you.

Take care.
