"She already judged a book without reading it."

Never judge a book by its cover

If your unhappy and stressed it telegraphs to the child,get a ticket and fly back to spend quality time with your mum,tell your husband its best for you and the baby,because if you have to live with your in-laws he might be minus a mum because you can feel your rage growing due to post-natal anger Go and visit your mum,you know you want to,think how much joy she would feel seeing the baby and its a lot less stressful for you right?
