The sleepless side of parenting

Being a parent is definitely not always easy. Especially when you are trying to get a little one to sleep in their own bed after 18 months of sleeping right next to you. I have tried for months to gently wean him off the boob at night and sleep alone...it hasn't worked. So, it's time to bring in the big guns and let him cry-it-out. A tactic that I am less than thrilled about but have no other ideas on what to do. He is very unhappy with me. I HATE listening to him cry "Momma, Momma, Momma" over and over as he throws himself against the door. He cried for two hours yesterday before he fell asleep. I will go in there every 20 minutes, give him a hug and say, "Lochlan it's time to sleep. Lay your head down and close your eyes." We are on day three of this torture. Bed time does not seem to be as difficult as nap time. He does NOT want to nap. He got so mad today he threw up all over himself and his bed. The most frustrating part is there are no real answers. There are not any fool proof systems to get your child to learn to relax on their own. Every child is different. I feel so bad but I can not nurse him all night long anymore. He is getting to big to be in our bed and after almost two years of not sleeping through the night this Mom is VERY, very tired. I read that 65% of parents have struggles when it comes to sleeping. At least I am not in it alone.
