My DD who has recently turned 2 is amazing, she's bright, funny, beautiful and very clever but from day 1 she has been so demanding. Even from being a newborn she never went down for naps, screamed if anyone else held her and fed every 40 minutes day and night. She didn't sleep through properly until she was past 13 months and even then we have 2 hourly battles every night to get her to sleep. All of which I have coped with and tried not to go too crazy! But even now her behaviour is so hard to deal with. She crys a lot. She walks round the house screaming constantly and follows me around doing it. She will scream and cry mummy, mummy, mummy repeatedly. She is only happy if I give her 100% of my attention and wants me to pick her up carry her all the time which ATM is hard as I am 11 weeks pregnant, feeling very sickly and she is the size of a 4 year old!!! 
I just feel exhausted by her constantly. My DS was nothing like this and much easier going. Her Dad is great but she screams for me the whole time she is with her. I'm finding it very hard not to get angry at her as age is basically in my face the whole time she is with me!
I feel like she has been such hard work and feel like surely we are due for her to grow into a new more pleasurable stage! Has anyone had any experience of this? Can help me handle it or even shine a light at the end of this very dark tunnel??
