Ok mommys need some help. I am trying to sleep train my son and it's not working. He will only take naps in my arms and if I put him down he is wide awake again. He does cuddle in my arms at night then I can put him in his crib. But how can I get him to go to sleep on his own. I will not try the cry it out I have anxiety and panic attacks so that don't work for me. Can anyone help me out with this.
