I am so frustrated and I really don't understand this attitude that I get my from my dad and his dad... All they do is point out the things I can't do anymore, how hard things are going to be, no sleeping... Every possible negative that could come out of having a child they throw in my face. All I want to do is scream " shut the fuck up!!" I know there will be things that are so hard I will think about giving up... And I know that will happen over and over again. I'm almost 36 weeks and I have thought about giving up multiple times already! But every kick gives me strength, every wiggle and every pain reminds me of the miracle I am growing. I don't sleep well now and sometimes I cry because of the pain I'm in, but I am growing a human being that I would do anything for. I don't think about sleepless nights... I think about comforting my crying baby boy when he's upset at night... Or feeding him every couple hours and bonding with him even when I am so tired I want to give up or give him to first available pair of arms for a well needed nap!!! I am a positive person and I know I have a lot to learn but I will be a an amazing mom to this boy no matter how many times I want to give up, no matter how many times I cry because of the pain or cry because I'm so tired I could fall asleep walking. I love my baby, and I am looking forward to the amazing moments full of love for my little boy... Not the things I might be "missing out on". Screw my family if they aren't willing to support me through this.
