Many of the books talk about bonding with your new born baby but if you have suffered from mental health issues as a new mother bonding difficulties can continue at a later stage.
Recently a mum asked for ideas to help this. I reassured her by saying that many children will express a preference at times for their dad, grandparents or significant other. As a recovering mum this can make you feel even more guilt and convince you that you are a failure! It can be so very hard when they reach out to others when you so need them to want you.
Be patient. Be kind to yourself and the bond WILL grow.
