I feel for you, it is such an exciting time in your life. You need to talk to your Nan and other rellies who haven't acknowledge your pregnancy. Do you see them often - as it is a bit obvious now and very rude of them not to mention anything to you!!! Did you personally tell the rellies that you were pregnant or did it come second hand. Family are sometimes funny and won't acknowledge anything until they are told personally (we can choose our friends!) Take your ultrasound pictures with you and sit with your Nan and tell her how excited you are about becoming a mum. If you don't see her - maybe send her a nice card explaining how you can't wait for her to meet her new great grandchild with photocopies of your ultrasound. Talking is the best way to solve problems, remember hormones are racing so just keep a level head and keep cool even though you may want to pop them one!
