Just Not Getting It Right

Sorry I have been so quiet, things have just been so hectic with Daniel and Joshua!They almost 2 months old. Time really does fly! Ok, not in the moment, but when I look back, I cant believe 8 weeks have already passed!
They have grown so much and I still sometimes cant believe that they are actually mine.

Now for the moaning:
I am struggling to get them into a proper routine. I am trying so hard, but it just doesnt seem to work. Add to that both of them are colicky, and Joshua doesnt sleep! I am tired. I have never been so tired in my life. Sleep deprivation is the worst form of torture, I have decided!
I just dont know what I am doing wrong. I have followed everyone's advice, but still I am not getting it right. People are telling me that they should be in a routine by now, and I ahave spoken to a few twin moms, and all their babies were in a strict routine by this stage, and they were already sleeping longer hours.

I feel so incapable. Why am I battling so much? Will I ever get this motherhood thing right?
