The subject head says it all really-i have a five week old little girl and a two year ten month old little boy. My husband works abroad and went back ten days ago so im doing it all by myself and am so tired, physically and emotionally. I have no family nearby for a break, and although my little boy goes to nursery a few mornings my daughter tends to be awake then and cries like crazy if not being held. I feel so guilty 'cos im yelling far too much at my son who seems to be pushing every button and tantruming like crazy. He's a lovely little chap but is trying it on big time and im not responding in the right way-i know im not but am so tired that i become a demon mummy. Anyway -just looking for moral support really- i know it will get better and am trying to take a day at a time but any tips for managing behaviour with a new arrival would be gratefully received.
