I needed to realise that I could not be good to my son until I had taken the time to take care of myself first. For me, that meant asking for help when I could. More importantly it meant forgiving myself when I couldn't do it all. Kids are pretty strong, they will get by. What is important at this time is that you take care of yourself.
Kids grieve too.
My son was looking forward to having a little brother or sister. When he realised he was not going to have one after all he felt confused and upset. He began to act out and seemed angry at the world. We did not know what had caused this behaviour. Finally one day I sat down with him and decided to ask him what was wrong.
