Hang in there Mama! I have three boys (10,4, and 14months) my two younger boy did this to me from birth until about 2 and my infant(Jonah) is doing the  same thing. I am a budding real estate agent in Gresham and I got pregnant shortly after getting my license. Ever since I gave birth he does not leave my side! I tried to do some site work for only a few hours a week to boost my career and he screamed the entire two hours I was gone! My poor mother-in-law was so good about it but I decided to stop because it just broke her heart when he refused to go to her because he thought that meant I was leaving and he would start crying. He is getting a little better now but still is very clingy, whatever shall us working mothers do!! I try to work some times and he is crawling all over my laptop and I have to try and be patient. All I have to say is we are a rare and dying breed(those mothers who try to work from home with children). Well Kudos to you!!
